What changes when you switch.
The same pull request, reviewed with less in the way.
01Unchanged screenshots are freeArgos counts every snapshot stored for a build. We receive a hash for each screenshot and upload only the ones we have not seen.
02The diff runs on your runnerThe CLI compares with the baseline on your runner and uploads the diff image, so our server only stores bytes. That is why storage is the only line on the bill.
03Free for teams, with no pauseArgos Hobby is for personal projects and pauses uploads at 5,000 screenshots. Our free plan has no limit on reviewers, and CI keeps passing at the storage limit.
What your reviewers get.
Each changed screenshot next to its baseline, with the changed pixels in magenta.
- Four views. Side by side, diff, slider and flip.
- Keyboard first. j and k to move, a to approve, r to reject.
- One check. Green when every change is approved.

What to know before you move from Argos.
Both review screenshots from your CI. Argos compares them on its servers and bills per screenshot. stateofpixel compares on your runner, uploads only new images and bills for the storage they use.
Yes. Each shard uploads its part, and the check reports once. Use --shard 2/4, or --shard auto with a finalize step.
Replace argosScreenshot() with snapshot() from stateofpixel/playwright, and the Argos reporter with stateofpixel/playwright.
The CLI warns at 80%. After 14 days over the limit, new images are not stored and the check passes with a note, so CI keeps passing.
