the AI bill of Argent
Buoy in our test of 14 app jobs, with its free and Pro tools. How we got these.
What you get for free
Your AI uses the app like a person does.
Read it, tap it, test it and check the logs. All with a free account.
Read the screen
describe_screen, native_inspect
Tap, swipe, type and pinch
tap_element, native_tap, native_swipe, native_type, native_pinch
Run steps in a row
run_flow
Take pictures and videos
screenshot_component, screen_recording
Work the device
device_control, reload_app, navigate, get_routes
Read logs
get_console
See the list of web calls
get_network_requests
Get a quick summary
get_triage
Two of these have a Pro part. On free, get_network_requests shows the list of web calls, but not what was sent or what came back. get_triage shows the names of saved keys, but not their values.
What it saves
A free tool can still cost you.
You pay while your AI waits. You also pay for every token it uses. We gave the same AI 14 jobs in our test app, 3 times each.

For a team of 6 devs, where each dev's AI does 20 app jobs a day.
Fair notes: this was one test, on our own app. We tuned Buoy on these jobs. The race used Buoy's free tools and its Pro tools, and we have not timed Free alone. The team numbers are a guess, built on a $150,000 salary.
What Pro adds
See inside your app.
Seeing inside the app is a big part of why Buoy was fast. The AI reads the app's data and web calls right away, so it guesses less.
State in Zustand, Redux, Jotai and React Query
Saved values, and edits to them
Web call bodies, mocks and slow or broken networks
The clock, location, permissions and app lifecycle
Time Machine and scenarios
Render checks, benchmarks and JS thread profiling
Sentry, images, assets, three.js, camera and the sim farm
If your AI calls a Pro tool on a free account, the tool says it needs Pro. Nothing is sent to your app.
