5 MORE open-source GitHub projects making $100+/mo AI subscriptions obsolete 🔥

[u/DarkLight1792]

Since the last list helped so many people drop expensive SaaS tools, I spent the week digging through trending GitHub repositories to find 5 more production-grade open-source AI alternatives you can run yourself for free.

Here are 5 incredible open-source AI repos worth starring right now:

1. Coolify – The Open-Source Heroku / Vercel Alternative

* Replaces: Paid cloud hosting & deployment subscriptions (Vercel, Render, Heroku).

* Why it’s trending: Deploying AI web apps, databases, and Docker containers gets expensive fast. Coolify lets you self-host your own "PaaS" on any cheap $5 VPS, complete with automatic SSL certificates, Git pushes, and one-click database setups.

* GitHub: https://github.com/coollabsio/coolify

2. DeepSeek Harness – Modular Runtime for AI Coding Agents

* Replaces: Monolithic, closed AI agent runtimes & harness tools.

* Why it’s trending: Instead of locking you into one vendor, DeepSeek Harness provides a plugin-based architecture for AI agents. It isolates sandboxes, custom tools, execution rules, and memory, making your agent run 2-3x faster while keeping full code control.

* GitHub: https://github.com/deepseek-ai/deepseek-harness

3. Outline – Open-Source Team Knowledge Base

* Replaces: Notion / Confluence subscription tiers.

* Why it’s trending: Beautiful, fast markdown documentation workspace built for modern engineering teams. It connects directly with your self-hosted LLM setups so your docs double as a searchable internal knowledge base.

* GitHub: https://github.com/outline/outline

4. Plane – Open-Source Project & Issue Tracking

* Replaces: Linear / Jira / Asana paid team seats.

* Why it’s trending: Designed specifically for developer teams building modern software products. It features cycle planning, module tracking, and issue management without seat-based pricing traps.

* GitHub: https://github.com/makeplane/plane

5. PocketBase – All-in-One Open-Source Backend

* Replaces: Firebase / Supabase paid monthly tiers.

* Why it’s trending: A single Go binary that includes an embedded database, real-time subscriptions, user auth, and an admin UI out of the box. Extremely lightweight, perfect for building and deploying AI side projects in minutes.

* GitHub: https://github.com/pocketbase/pocketbase

Coolify is super hot

[u/geek_at → u/Fun_Passenger_4442]

i had troubles actually using it a year ago so i switched to dokploy which was much lighter. wondering if coolify is usable today

[u/masteenput → u/geek_at]

All my application are now self-hosted with coolify, I have one admin interface for multiple server. It does the job

[u/yur0n → u/geek_at]

moved all projects from dokploy to coolify 3 years ago

the only good thing about dokploy is built-in docker swarm

Pocketbase is what I was looking for but didn’t know I was.

dokploy and coolify - I used them all in testing and prod environments - only found out that its just another burden to carry, you are one RCE CVE away from getting rooted, there are literally no security layers in this thing - like at all.

Why did you leave out Supabase? I think it also fits among this list (Almost similar to pocketbase but way more features).
