Building blocks and infrastructure for developers

Awesome Selfhosted is a categorized catalog of free software for running web applications and network services on infrastructure you control. It covers areas such as analytics, backups, bookmarks, communication, generative AI, project management, wikis, and self-hosting platforms, with entries commonly listing websites, source code, licenses, and technology stacks. It helps with discovery and comparison rather than installation or hosting.

Browser Use gives an AI agent direct browser interaction for navigation, clicking, typing, and form completion. The CLI is designed for one-off browser tasks driven by an existing agent such as Claude Code or Codex, while the Python library supports repeatable automation, parallel jobs, custom tools, and product integrations with a model provider of the developer's choice.

Playwright drives Chromium, Firefox, and WebKit through one API for end-to-end testing and general browser automation. It can be used as a test runner or library, through a CLI designed for coding agents, or through an MCP server for LLM-driven workflows. Its VS Code extension also supports test recording, debugging, locator picking, and trace inspection.

Daytona lets agents create isolated compute sandboxes through SDKs, an API, or a CLI, then execute code, manage files and processes, and preserve state with snapshots. Clients are available for several languages, including Python and TypeScript. This public repository has been unmaintained since June 2026 because core development moved to a private codebase, so it receives no further fixes or support.

This curated directory helps designers and frontend developers find resources for interface work without searching each category from scratch. It groups stock imagery, illustrations, fonts, icons, web templates, CSS frameworks, UI component libraries, design systems, and related tools, with a short description for each link to make scanning and comparison easier.

Mem0 stores user, session, and agent state so assistants, support bots, and automated systems can recall preferences and prior interactions. Developers can integrate it through Python or JavaScript libraries, a CLI, a self-hosted server, or the managed platform. Its core workflow depends on an LLM and an embedding model, and some managed-platform optimizations are not included in the open-source SDK.

AutoGen provides multi-agent orchestration, tool use, and a visual studio for prototyping workflows in which agents work autonomously or alongside people. The project is now in maintenance mode and will not receive new features. Existing users can continue using it or follow the migration guide, while new projects are directed to Microsoft Agent Framework.

PrivateGPT sits between an OpenAI-compatible local inference server and the applications built on top of it. Its API covers messages, file ingestion, citation-backed retrieval, custom tools, database and CSV access, and MCP connectors, following the Claude API as a reference. The included web interface is mainly a demonstrator and debugger; developers are expected to build their own user experience around the API.

Appwrite brings common application backends into one platform so web, mobile, and AI teams can avoid assembling a fragmented stack. It covers identity and data management, file storage, server-side functions, realtime communication, and web hosting. Teams can use the managed cloud or self-host in Docker, Kubernetes, and other container environments, then connect through SDKs or REST, WebSocket, and GraphQL APIs.

LiteLLM works as either a Python SDK or a self-hosted AI gateway, exposing more than 100 providers through a unified OpenAI-compatible interface. Teams can switch among services such as OpenAI, Anthropic, Gemini, Bedrock, and Azure without rewriting every integration, while centralizing virtual keys, spend tracking, load balancing, logging, and guardrails at the gateway.

This collection organizes Cursor Project Rules for frontend, backend, testing, security, and other development scenarios. Developers can place selected .mdc files in a project's .cursor/rules/ directory so Cursor follows the codebase's architecture, preferred libraries, and team conventions.

LangGraph is a low-level orchestration framework for long-running, stateful workflows and agents. It supports durable execution that resumes after failures, persistent state, and human-in-the-loop control for tasks with branches, loops, or extended runtimes. Developers can use it independently or combine it with models, tools, and observability services from the broader LangChain ecosystem.

Awesome Sysadmin is a categorized directory for sysadmins, DevOps engineers, and SREs looking for open-source software. It spans backups, configuration management, CI/CD, deployment, monitoring, platform services, VPNs, and more, with entries typically showing source links, licenses, and implementation languages; it is a discovery list, not an operations platform.

Dokku is a small, self-hosted platform as a service that turns a Linux virtual machine into a Heroku-like environment for building and managing application lifecycles. It suits individuals or small teams that want control of the host without operating a larger cloud platform. The documented setup requires a supported Ubuntu or Debian machine and an SSH key, followed by configuration of the server domain and user access.

WebTorrent provides one JavaScript BitTorrent client for browsers and Node.js. It exposes files as streams, so applications can play or seek before a download finishes, and it can also seed files. Browser clients use WebRTC without plugins and can connect only to WebTorrent/WebRTC-compatible peers, while the Node.js client communicates with conventional peers over TCP and UDP.

Proxmox VE Helper-Scripts is a community collection for installing hundreds of self-hosted services as containers or virtual machines. Users find a service on the project website, paste its command into the Proxmox shell, and choose either sensible defaults or advanced resource, network, and storage settings. Post-install helpers handle updates, configuration changes, logs, and basic troubleshooting. A supported Proxmox VE host, root shell access, and an internet connection are required.

smolagents offers a compact Python framework for code-writing agents, conventional tool-calling agents, and multi-agent hierarchies, with support for different model providers and Hub sharing. Its CodeAgent expresses actions as Python snippets. Since those snippets are executed, untrusted workloads should use a sandboxed backend; the local Python executor is explicitly not a security boundary.

Awesome Electron is a curated index for people building desktop applications with Electron. It groups reference apps, boilerplates, packaging and distribution tools, debugging utilities, articles, and videos so developers can compare approaches or find starting points; the repository is a resource list rather than an application framework or generator.
