Free alternative
to GitHub Copilot.
GitHub Copilot Pro is $120/yr for completions and chat inside your IDE. RareMatter hands whole tasks to agents — planning and running included — for $0.
| GitHub Copilot | RareMatter | |
|---|---|---|
| Price | $120/yr (Pro) | $0 — 100 Atoms every day |
| Style | Autocomplete + chat sidebar | Task-first agents |
| Where | VS Code, JetBrains, GitHub | Browser (no IDE needed) |
| Free tier | Limited completions | Full preview, daily refill |
| Lock-in | Microsoft account + billing | None — open and leave |
Honest take
Where GitHub Copilot
wins anyway.
- Copilot's completion inside VS Code is muscle memory for millions.
- Free tier exists and is usable for light use.
Verdict
The math
isn't close.
Copilot autocompletes the line you're writing. RareMatter asks what you're actually trying to ship, plans it, builds it, and runs it. Completion is a feature; agency is a product. One costs $120/yr forever — the other refills to 100 Atoms at midnight and charges nothing.
