Not copied from the project's own blurb. These are things we opened and verified, with the date.
- 7 Sept 2026We checked that the link to the project still resolves.
- 14 Aug 2026We read the licence text itself (LICENSE). No unusual restrictions were stated.
- 1 Sept 2026We read the project's own documentation and found no sign that development has stopped.
Where this sits among the 114 tools we list in AI agents
- Keeps your data on your own machine11 of 114
- Commercial use confirmed as allowed95 of 114
- Requires terminal commands21 that do not →
- Requires an API key29 that do not →
Only 11 of the 114 meet all of the conditions above.
Counted from our own checks: every tool we list is examined against the same criteria.
What it does
Switches between OpenAI, Anthropic, Google and other providers in a single interface, and will send the same prompt to several at once so you can compare answers — alongside image generation, PDF reading and the usual chat workspace features. Self-host via Docker or Vercel, or use the hosted build; keys and their costs are yours. Beam-style multi-model queries bill per provider, which is worth internalising before you make it a habit.

big-AGI FAQ
- Is big-AGI free?
- big-AGI itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
- Do I need to install anything or write code to use big-AGI?
- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does big-AGI work on a phone?
- No. It needs a computer.
- Can I use big-AGI commercially?
- The licence is MIT, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
