The best self-hosted GitHub projects share one idea: instead of renting software by the month, you run it on your own server and keep control of your data. Self-hosting is not free in the full sense — you still need a server, updates, and backups — but for many people the trade is worth it. The five projects below are proven, well-starred starting points, from a master list to tools for PDFs, voice, deployment, and social scheduling. Star counts were checked on GitHub on 30 October 2026 and change daily.

Awesome Self-Hosted (awesome-selfhosted/awesome-selfhosted, 331,907 stars) is a list of free software network services and web applications you can host on your own servers. It is the right first stop, because it organises projects by category — media, photos, documents, analytics, dashboards, and more — so you can find a tool for one job instead of guessing. Use it to shortlist two or three options for a single need, then compare their installation guides before committing.

Stirling-PDF (Stirling-Tools/Stirling-PDF, 95,384 stars, TypeScript) is a PDF application that lets you edit PDFs on any device anywhere, according to its own description. In practice it covers the everyday PDF jobs people otherwise pay for: merging, splitting, compressing, converting, and signing documents, all from a web interface you host yourself. It suits small teams and individuals who handle PDFs daily and want those files to stay on their own infrastructure.

VoiceStudio (debpalash/VoiceStudio, 94,665 stars, Python) is the open-source, fully-local ElevenLabs alternative for voice cloning, voice design, video dubbing, dictation, transcription, and audiobook creation in 646 languages. Because it runs locally, your audio does not leave your machine, which matters for sensitive recordings. One honest caveat from its own documentation: its default voice weights carry a non-commercial licence, so check the licence before using generated audio in paid work.

Coolify (coollabsio/coolify, 65,288 stars, PHP) is an open-source, self-hostable platform alternative to Vercel, Heroku, and Netlify that lets you deploy static sites, apps, and databases with a Heroku-like experience. If you have a server and want push-to-deploy without a platform bill, Coolify is the layer that makes self-hosting feel manageable. It suits developers who already run a VPS and want to host several small projects from one dashboard.

Postiz (gitroomhq/postiz-app, 40,151 stars, TypeScript) is an agentic social media scheduling tool: it helps you plan and publish posts across social channels from one place, with AI-assisted scheduling. For a small team or creator, it replaces a separate scheduling subscription, and because you host it yourself, your account connections and drafts stay under your control. Check which networks it supports before you switch, since social platforms change their API rules regularly.

Before you self-host anything, answer three questions. First, do you have a server you will actually maintain, including security updates and backups? Second, does the project have recent commits and clear Docker or installation docs? Third, is the licence compatible with how you plan to use it, especially for business use? If the answer to any of these is no, a hosted service may still be the better choice.

FAQ: Is self-hosting really free? The software is free, but you pay for the server, your time on updates, and sometimes for third-party services the tool connects to. FAQ: Do I need Linux skills? Most of these projects offer Docker setups, which help, but basic comfort with a server and the command line makes troubleshooting much easier. FAQ: What should I host first? Pick one tool that solves a daily pain, such as Stirling-PDF for documents, and get it running reliably before adding more.
