What we checked ourselves
Not copied from the project's own blurb. These are things we opened and verified, with the date.
- 23 Aug 2026We checked that the link to the project still resolves.
- 14 Aug 2026We read the licence text itself (null). No unusual restrictions were stated.
- 31 Jul 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
- No API key required29 of 114
- Commercial use confirmed as allowed95 of 114
- Requires terminal commands21 that do not →
- Sends your input to the provider11 that do not →
Only 24 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
Treats each component the way an OS treats a process — a sealed WebAssembly capsule that composes with others, receives only explicit authority, and can be replaced without widening its reach. The kernel is deliberately small: route events, enforce capabilities, get out of the way. It is independent of any model provider, agent loop or product, and it is infrastructure for people building agent systems rather than something an end user installs. Whatever you do grant is still fully exercisable, so the grant design is the security. Apache-2.0.

astrid FAQ
- Is astrid free?
- Yes. It runs on your own machine, so there is no usage-based cost either.
- Do I need to install anything or write code to use astrid?
- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does astrid work on a phone?
- No. It needs a computer.
- Can I use astrid commercially?
- The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
