Codai Resolve

Bug fixes, proven by tests.
No fix, no fee.

Submit a GitHub issue. Get back a patch with executable proof: a reproduction test written first, the fix that makes it pass, and your regression suite kept green. If Resolve can't verify the fix, you pay nothing.

what a failed attempt costs you

How it works

Repro fix verify attest

01

Submit the issue

Point Resolve at a public GitHub repo and paste the issue (or a failing test command). Triage quotes a flat price in seconds — or declines free of charge.

02

Repro first

The agent writes a reproduction test that must FAIL on your current code before any fix is attempted. No repro, no bill.

03

Fix + verify in sandbox

Candidate patches run in an isolated sandbox: the repro must flip to PASS and your existing test suite must stay green. Failed attempts are never billed.

04

Attestation, then payment

You get a shareable proof: the exact patch, the repro test, before/after test output, and the runner image digest. The charge exists only after the proof does.

The guarantee

You pay for outcomes, not attempts

No fix, no fee

Billing is wired so a charge row can only be created after a verified attestation. Failure and infrastructure errors cost you nothing — by construction, not by policy.

Verification never fails open

A broken environment or a timeout marks the job failed — it is never "probably fine". Every claim in the attestation is backed by executed tests.

Proof you can share

Attestations are public-by-URL JSON documents. Hand the link to your team, CI, or auditor — the patch, tests, and outputs are all there.

Minutes, not sprints

Typical single-function bugs resolve in under 10 minutes end-to-end, including repro authoring and full regression verification.

Pricing

Flat price per fix, quoted up front

Triage reads your issue and quotes one of three flat prices — or declines for free if the bug isn't a good fit. Your first 3 verified fixes are on us.

$7

Simple

Single-function bugs with a clear repro path.

$19

Standard

Multi-file logic bugs, moderate investigation.

$49

Complex

Cross-cutting bugs needing deep repo context.

Declined triage, failed attempts, and infrastructure errors are always $0.

Ship the fix. Keep the proof.
