Agents write the code. Opslane proves it works.

Opslane opens your app in a real browser, clicks through what the PR changed, and posts screenshots, video, and data checks as proof it works.

Task → acceptance criteria → proof

Animation of an Opslane verification run in three steps. First, a task — add promo codes to checkout — is assigned to a coding agent, which opens a pull request. Second, Opslane derives acceptance criteria from the PR. Third, a real browser runs each criterion: the promo field renders, SAVE20 applies a discount, but an expired code is accepted and charges full price. The report resolves each check with screenshots, video, and data checks attached as evidence, and the merge is blocked.

How it works

Spin up. Run. Prove.

· 01

Every PR gets an ephemeral environment.

Opslane builds and boots a throwaway copy of your app from the PR branch — fresh data, destroyed after the run. No shared staging, nothing to wire up.

· 02

It runs the feature in a real browser.

Real Chromium clicks through what the PR changed, capturing screenshots of every state, video of the full flow, and data checks that the signup actually created the row.

· 03

Proof lands on the PR. Red blocks the merge.

A pass/fail report with the evidence attached. You review a screenshot gallery instead of re-running the code in your head.

Why verification

Writing code is no longer the bottleneck. Verifying it is.

I “Accept All” always. I don’t read the diffs anymore.
Andrej Karpathy · on vibe coding
I became fully verification-pilled… for every pull request that Claude is putting out, there is an attached photo or video. That helps you gain a lot of confidence.
Mike Krieger · Chief Product Officer, Anthropic

Reads vs. runs

Reviewing code isn’t running it.

Keep your code reviewer. It just can’t tell you the checkout completes — only running the checkout can.

AI code review

  • Reads the diff
  • Predicts what might break
  • Posts opinions about the code
  • No proof the app still works

Opslane

  • Boots your app in an ephemeral environment
  • Runs the feature in a real browser
  • Posts evidence: screenshots, video, data checks
  • Blocks the merge when a flow goes red

Real evidence

Real apps, real evidence.

We pointed Opslane at open-source codebases. Each card opens the full report it produced — every flow, with the recording to prove it.

FAQ

What does Opslane actually post on my PR?
Evidence. Screenshots of every flow it ran, a video of the full run, and data checks (did the signup create the row, did the webhook fire). Plus a pass/fail verdict that gates the merge.
How is this different from AI code review (CodeRabbit, Greptile, Copilot)?
Those read the diff and predict whether it's correct. Opslane runs the code. A static review can't tell you the checkout actually completes — a recording of the checkout completing can.
Do I need to write test scripts?
No. Opslane figures out what to check from the PR. No Playwright scripts, no Cypress config, no test files to maintain.
Do I need a staging environment?
No. Opslane spins up an ephemeral environment for every PR — an isolated copy of your app with fresh data, destroyed after the run. No shared staging slot, no preview URLs to wire up.
Can I see Opslane proving a real public repo works?
Yes — scroll up to the "Real apps, real evidence" section. Each card opens the full report Opslane produced on an open-source codebase.
What stacks does it work with?
If it runs in a browser, Opslane can verify it. React, Next.js, Vue, Svelte, Rails, Django... doesn't matter.
Is my code safe?
Opslane is open source. Your code runs in throwaway sandboxes that get destroyed after each run.
How is this different from Playwright or Cypress?
Those are frameworks for writing and maintaining test scripts. Opslane runs on every PR with zero setup and posts the evidence. You don't write tests. You don't maintain tests.
