Flux, Modern API Client
Native API client. AI built in, no key, no account.
0.2.0 makes the AI free to try: 100 actions a month, no API key and no setup. Before this you had to bring your own Anthropic key before you could see what it did, and most people never got that far. The CLI now embeds a JS engine and the same pm shim as the app, so collections that authenticate through a pre-request script finally run in CI instead of being skipped with a warning. Three assertion engines that had drifted apart are now one. Still Tauri, not Electron. Still open source.
I launched Flux here two months ago with a problem I had built in
myself: the AI features needed you to go get an Anthropic key, paste
it into settings, and only then could you see what they did. Most
people never got past step one. Fair enough.
0.2.0 removes that step. Sign in and you get 100 AI actions a month,
20 a day, no key and no setup. Point it at a failing endpoint and it
writes the assertions, explains the 4xx, or fixes the broken test.
Being straight about how that works, because you would ask anyway:
free-tier prompts go through a small proxy of ours that checks your
quota and forwards the call with our key. Your prompt, including any
response body you are debugging, passes through our server. If that
is not acceptable for what you work on, add your own key: nothing is
relayed, calls go straight from your machine to Anthropic, and every
limit disappears. Both modes ship in the app, one toggle apart. I am
not putting a shared key inside the binary, since it would be
extracted from the first download.
The other half of 0.2.0 is CI. The Flux CLI now embeds a JS engine
and the same `pm` shim the app uses, so a collection that
authenticates through a pre-request script actually runs in your
pipeline. Auth, query params, GraphQL, form bodies and nested folders
made the jump too.
And one bug worth naming out loud: an unrecognised assertion path used
to resolve to null, so `anything.at.all == null` passed against any
response, and exited 0 in CI. If your Flux pipelines have been
suspiciously green, this release will start telling you the truth.
Load testing and mock servers are in there too, no paid tier. Still
Tauri, not Electron. Still open source.
Happy to answer anything, especially about the proxy.
