FAQ
Comparison FAQ
Is Liminal a good Cursor alternative?
If you want an agent that runs outside a single editor, supports any model, costs $0 for the software, and shows every tool call — yes. If you want deep inline completions inside VS Code fork, Cursor may fit better. Many developers use both.
Can Liminal replace ChatGPT for coding?
For tasks that need reading your repo, editing files, running tests, or browsing docs — Liminal is stronger because it acts, not only advises. For brainstorming or writing prose, ChatGPT is still fine.
Is Liminal better than GitHub Copilot?
Copilot excels at inline suggestions while you type. Liminal excels at multi-step autonomous tasks across the whole project. Different jobs.
