Keycloak is a complete identity and access management platform that gives your applications login, registration, single sign on, and multi factor authentication, all running on infrastructure you control. Backed by Red Hat and the Cloud Native Computing Foundation, it is one of the most widely deployed self hosted identity platforms in the world. It implements OpenID Connect, OAuth 2.0, and SAML, comes with passkey (WebAuthn) support and social login (Google, GitHub, Microsoft, and more) built in, and exposes a full admin API for managing realms, users, and applications programmatically. Its realm based architecture lets you keep multiple isolated user pools, each with its own login policy, branding, and clients, inside a single instance. Deploying Keycloak on CloudRaya means you get a production ready identity platform running in minutes, with your database credentials and internal secrets managed securely and automatically, so you can focus on wiring up login for your actual product. This deployment is best suited for small to medium teams, running as a single instance with a Postgres database behind it. Use cases Centralized login and user management for a SaaS product or internal tool Single sign on across multiple internal apps and services Social login integration with Google, GitHub, Microsoft, and other OAuth or OIDC providers Passkey and multi factor authentication for higher security applications Running your own self hosted identity layer instead of building login from scratch Isolating separate user pools (for example, staff versus customers) using realms within one instance Why Keycloak on CloudRaya Deploy a full identity platform in minutes without managing servers or infrastructure yourself Fully open source under Apache 2.0, no paid tiers, feature gates, or per user pricing to worry about Database credentials and internal secrets are generated and managed automatically per deployment Passkey and social login are available out of the box, no separate license or add on required Full REST admin API for integrating with your existing stack Easy to move to a custom domain once you are ready to go live Keycloak on CloudRaya allows teams to quickly deploy a powerful identity and access management platform without the complexity of managing servers. Recommended resource package Minimum: Small package (2 CPU, 4GB RAM), good for testing or a light development instance. Keycloak runs on the JVM and, according to Red Hat's own sizing guide, a single instance uses roughly 1 to 1.25GB of RAM at baseline before serving any real traffic, so Nano is too tight once Postgres is factored in. Recommended: Medium package (6 CPU, 12GB RAM), a solid production baseline for small to medium teams. Red Hat's guidance estimates roughly 1 CPU core per 15 password based logins per second, since secure password hashing is deliberately CPU intensive, this tier gives comfortable headroom for that plus Postgres. Production: Large package (8 CPU, 16GB RAM), for teams with higher concurrent login volume or larger cached session counts, since both memory and CPU needs grow with active sessions and login throughput.
LimeSurvey is a powerful open source survey platform used by researchers, educators, NGOs, government institutions, and businesses to create and manage online surveys. With a full featured admin panel, support for 80+ languages, and advanced question types, LimeSurvey gives you complete control over your data without relying on third party survey services. Unlike SaaS survey tools like Google Forms or Typeform, LimeSurvey runs entirely on your own infrastructure. Your survey responses, participant data, and encryption keys never leave your server. This makes it the preferred choice for organizations with strict data privacy requirements, including healthcare, research, and public institutions. Deploying LimeSurvey on CloudRaya gives you a production ready instance in minutes, backed by persistent storage and a managed PostgreSQL database, with no server management required on your end. Use cases Academic and field research surveys with complex branching logic Employee satisfaction and internal HR surveys Customer feedback and NPS collection for businesses Government and NGO data collection with strict data residency requirements Event registration and pre/post event feedback forms Patient intake and healthcare questionnaires requiring data privacy compliance Why LimeSurvey on CloudRaya Full data ownership, survey responses stay on your own infrastructure Managed PostgreSQL included, no separate database setup needed Persistent file storage for uploaded survey media and assets Deterministic encryption keys derived from your deployment, safe across restarts SMTP configured via admin panel, no env variables needed for email setup One click deploy, production ready with sane defaults out of the box Recommended resource package LimeSurvey is a PHP application whose resource needs scale with concurrent survey respondents and question complexity, not just the number of surveys you manage. Minimum: Nano package (1 CPU, 2GB RAM), suitable for low traffic or personal use Recommended: Small package (2 CPU, 4GB RAM), suitable for team or institutional use with regular survey campaigns Production: Medium package (6 CPU, 12GB RAM), suitable for large scale survey campaigns with many concurrent respondents

Minimum: Nano package (1 CPU, 2GB RAM), genuinely sufficient for personal use and small teams, this is not just a testing tier Recommended: Small package (2 CPU, 4GB RAM), worth upgrading to if several team members write and search frequently at the same time, or if you store many attachments Production: Medium package (6 CPU, 12GB RAM), only needed for larger teams with heavy concurrent usage across many users
Paperlessngx turns a pile of scanned paper and loose digital files into a searchable, organized archive. Upload a document and it runs OCR automatically, so even a photo of a receipt becomes fully searchable text, then tags it with the correspondent, document type, and category it recognizes from your past documents. Think of it less as a heavyweight enterprise document management system with approval chains and compliance workflows, and more as a smart personal or small team archive. It is built for the everyday reality of scattered invoices, contracts, and paperwork rather than largescale corporate document governance. That focus is exactly what makes it fast to set up and easy for a small team or an individual to actually keep using. Deploying Paperlessngx on CloudRaya means the OCR engine, background task processor, and web app are already wired together and tested. You just upload documents and start searching, no server setup required. Use cases Keep a personal digital archive of important documents like warranties, ID cards, contracts, and certificates Digitize and archive invoices and receipts so they are easy to find during tax season or an audit Give a small business or freelancer a searchable archive of contracts, vendor agreements, and paperwork without a filing cabinet Replace a messy shared drive full of unorganized PDFs with a tagged, searchable archive Automatically pull invoices or statements into your archive from a monitored email inbox Give an accounting or admin team a shared, permission controlled document repository for day to day paperwork Why Paperlessngx on CloudRaya No infrastructure setup. OCR processing, background tasks, and the web app are pre wired and tested Runs on a lightweight single service setup, no separate database server required Full data ownership, your scanned documents never leave your own deployment Full text search across every document, including scanned images, powered by built in OCR Backed by an active open source project with frequent releases and security updates One click custom domain support so your archive can run on your own brand Recommended resource package Minimum: Nano package (1 CPU, 2GB RAM), personal use, light document volume Recommended: Small package (2 CPU, 4GB RAM), small team, moderate document volume Production: Medium package (6 CPU, 12GB RAM), larger team, heavy scanning and OCR volume
Penpot is an open source design and prototyping platform for product teams, often described as a Figma alternative. Built entirely on open web standards, it runs in the browser, supports realtime collaboration, and stores designs as SVG, CSS and HTML rather than a proprietary format, so files stay human readable, portable and free from vendor lockin. Because Penpot is open source under the MPL2.0 license and runs entirely on your own CloudRaya instance, there are no perseat fees and no centrally imposed feature gates, your team size and usage are limited only by your own resource tier, not by a vendor's pricing plan. This also means your design files, assets and version history live entirely on infrastructure you control, which matters for agencies handling NDA protected work, regulated industries, and any team with data sovereignty requirements. Running Penpot on CloudRaya simplifies the selfhosting setup. Penpot normally ships as a stack of separate services (a web frontend, a backend, an exporter with a headless browser, a cache and a database). On CloudRaya this is packaged into a ready to deploy app plus a managed PostgreSQL database, with HTTPS, secrets and storage handled for you, so you can have a private, selfhosted design platform running in minutes instead of hours. Use cases Run a self hosted design and prototyping tool that keeps all design files on infrastructure you control Maintain a shared design system with native design tokens and reusable components across multiple products Provide NDA safe or compliance sensitive design work for agencies, healthcare, government and finance teams Hand off design to code, since Penpot expresses designs as code that developers and AI tools can read directly Give open source communities a free, accessible design platform without commercial per seat licensing Run real time, multi designer collaboration sessions on your own private instance Why Penpot on CloudRaya No per seat fees, unlimited editors and projects on a single flat priced instance Full data ownership, your design files and assets never leave your CloudRaya environment The multi service Penpot stack is pre packaged, no manual wiring of frontend, backend, exporter and cache Managed PostgreSQL database with credentials generated securely per deployment Automatic HTTPS through the CloudRaya reverse proxy, so browser features that require a secure context work out of the box Custom domain support so you can use your own branded URL Penpot on CloudRaya allows teams to quickly deploy a powerful open source design platform without the complexity of managing servers. Recommended resource package Penpot is resource heavy. The app container bundles a JVM backend, a Node plus Chromium exporter and an in memory cache, with PostgreSQL running separately. Note that performance also depends on each designer's own laptop and network, since Penpot renders heavily in the browser. Minimum: Small package (2 CPU, 4GB RAM), Penpot's own documentation lists 4GB RAM as the floor for selfhosting, and this matches what we confirmed with a real deployment on this tier. It is a fit for you if you are a solo designer or a very small team doing light, lowtraffic work, think testing Penpot out or occasional design tasks rather than daily heavy use. Recommended: Medium package (6 CPU, 12GB RAM), comfortable for small to medium teams with regular concurrent editing, exports and moderately complex files. Production: Large package (8 CPU, 16GB RAM), for larger teams, higher concurrent editor counts, and frequent export or thumbnail activity.
PocketBase is an open source backend solution that provides a lightweight, allinone backend for modern applications. It includes a built in SQLite database, authentication system, file storage, and real time subscriptions, all packaged in a single self contained server. PocketBase is designed for developers who want to quickly build production ready backends without managing complex infrastructure. PocketBase is ideal for startups, prototypes, and production apps that need a simple yet powerful backend with minimal operational overhead. Use cases Backend for web and mobile applications SaaS MVP and rapid prototyping Authentication and user management systems Real time apps (chat, notifications, live dashboards) Internal tools and lightweight admin systems Why PocketBase on CloudRaya One click deployment with no infrastructure setup Built in SQLite database and file storage, no external database required Secure and isolated execution environment Persistent storage configured automatically Ready to use immediately after deployment PocketBase on CloudRaya allows you to focus on building your application logic without worrying about backend infrastructure or database configuration. Recommended resource package PocketBase is a single Go binary with an embedded SQLite database, one of the lightest backend platforms available, so most projects can run comfortably on the smallest tiers. Minimum: Nano (1 CPU, 2GB RAM), genuinely sufficient for most small to medium projects, including production use for MVPs, internal tools, and apps with moderate traffic Recommended: Small (2 CPU, 4GB RAM), worth upgrading to if you have many concurrent real time subscriptions, high file upload volume, or need extra headroom under GOMEMLIMIT Production: Medium (6 CPU, 12GB RAM) or higher, only needed for large scale applications with heavy concurrent traffic, large file storage workloads, or complex query patterns across many collections
Shlink is a selfhosted URL shortener that lets you create branded short links under your own domain, instead of relying on thirdparty shorteners. Every click is tracked with detailed visit analytics, including location, referrer, browser, and device, so you always know how your links are performing. Unlike generic shorteners, Shlink gives you full control over the domain your links use. Point your own domain at your Shlink instance, and every short link you create looks like it came straight from your brand, not a thirdparty service. Shlink also supports multiple domains from a single instance, dynamic and static QR codes for every short link, tagging and filtering, and a clean web dashboard for managing everything without touching the command line. Use cases Branded short links for marketing campaigns, social media posts, and email newsletters QR codes for print materials, packaging, or events that link back to trackable short URLs Internal link shortening for teams sharing long, unwieldy URLs (dashboards, tickets, documents) Running short links for multiple brands or product lines from one instance, each on its own domain Click and visit analytics to measure which channels are driving traffic Replacing paid linkshortening subscriptions with a selfhosted alternative you fully control Why Shlink on CloudRaya No server or database to manage. CloudRaya provisions everything, including a managed PostgreSQL database, automatically Your own domain, your own brand. Point any domain you own at your instance and every short link reflects it, not a thirdparty name Support for multiple domains on the same instance, useful if your company runs more than one brand or website Full visit analytics built in, with no external analytics service required Automatic HTTPS on both the default CloudRaya domain and any custom domain you add Open source and selfhosted, so your link data stays yours Shlink on CloudRaya allows teams to quickly deploy a powerful URL shortening and link analytics platform without the complexity of managing servers. Recommended resource package Minimum: Nano package (1 CPU, 2GB RAM), for personal use, testing, or light campaigns with a small number of links and moderate click volume Recommended: Small package (2 CPU, 4GB RAM), for teams running regular marketing campaigns across one or two domains with steady click traffic Production: Medium package (6 CPU, 12GB RAM), for highvolume campaigns, multiple active domains, or heavy use of visit analytics and QR code generation at scale Shlink itself is lightweight. The main factor that determines how much headroom you need is visit volume, since every click is logged and tracked, not the redirect itself, which is near instant.
Stirling PDF is a powerful, self hosted PDF toolkit with 50+ tools accessible through a clean web interface. It lets you merge, split, compress, rotate, convert, add watermarks, redact, OCR, sign, and more, all without sending your documents to third party servers. All files are processed locally on your own infrastructure. Documents are never stored permanently on the server. Files exist only in memory during processing and are discarded immediately after download. Use cases A self hosted alternative to tools like Smallpdf, ILovePDF, or Adobe Acrobat for your team Process sensitive business and legal documents without cloud exposure Batch PDF operations for document heavy workflows OCR for scanned documents and archival digitization API integration for automated PDF processing pipelines Why Stirling PDF on CloudRaya One click deployment with no infrastructure setup All PDF processing happens on your own server, zero data leaves your instance Secure by default, login required to access the instance Scalable serverless container architecture REST API included for automation and integration Stirling PDF on CloudRaya allows teams to quickly deploy a powerful document processing platform without the complexity of managing servers. Choosing a version Stirling PDF on CloudRaya is available in two versions. Choose based on your use case and available server resources: UltraLite Core PDF tools (merge, split, compress, rotate) Lightweight processing (no heavy dependencies) No OCR, no LibreOffice, no advanced conversions No builtin authentication system (login feature not available by default) Image size: approximately 300 to 700MB Best for basic PDF operations, low resource environments, and fast, stable usage on small containers. Fat All PDF tools and advanced features OCR (Tesseract) DOCX / XLSX to PDF conversion LibreOffice (preinstalled) Full font support All conversion formats Builtin authentication system (supports SECURITY\ENABLELOGIN) Image size: approximately 2GB or more Best for full document processing workflows, OCR and advanced conversions, and secure environments requiring login and user management. Key differences and implications UltraLite removes heavy dependencies, which means no OCR, no authentication system, no Office document conversion, and no advanced format conversions, but it stays fast, lightweight, and stable on minimal resources. Fat includes all dependencies and security features, which means full feature access including OCR and conversions, and login and user management are available, but it comes with higher memory consumption. For full details about version differences, refer to the official documentation at https://docs.stirlingpdf.com/Installation/Docker%20Install/choosingyourversion Recommended resource package Minimum: Nano package (1 CPU, 2GB RAM), for the UltraLite version handling basic PDF tasks such as merge, split, compress, and rotate. UltraLite skips heavy dependencies like OCR and LibreOffice, so it stays comfortably within Nano's capacity Recommended: Small package (2 CPU, 4GB RAM), for the Fat version with full features including OCR, Office document conversion, and login. Fat already uses close to 2GB just to run, before processing any file, and tasks like OCR or converting Office documents need extra memory on top of that, so Small gives enough room to avoid running out of memory Production: Medium package (6 CPU, 12GB RAM), for the Fat version under heavier or more frequent usage, such as batch OCR processing, multiple concurrent conversions, or several users uploading large files at the same time A quick way to choose between versions: if you do not need OCR, Office file conversion, or builtin login, UltraLite on Nano is the more stable and cost effective option. If you need any of those features, use the Fat version, and give it at least Small, since Fat already needs close to 2GB just to run before you even open a file. If your Fat version container keeps restarting, check the Logs tab in your CloudRaya panel. An OutOfMemoryError there means your selected package does not have enough RAM, upgrade your resource package or switch to the UltraLite version if the missing features are not needed.
