Stoney finds them across your code, PRs, and tickets — then catches every PR that would break one and flags every ticket that contradicts another. Engineering and product, finally on the same page.

Five things nobody else does

Every other tool tells you
something broke.
Stoney tells you why.

Five capabilities only Stoney can ship, because only Stoney correlates your code, your PRs, and your tickets into a single ledger with provenance.

Drift forensics, not drift alerts

When a rule breaks, Stoney names the PR that caused it, the author, the exact diff, and the ticket the change now contradicts. Every other tool says something's wrong. Stoney investigates.

Pre-merge rule check on every PR

Open a PR, Stoney compares the diff against the rules your code enforces today, and posts an inline GitHub Check. If your change would break rule X or contradict rule Y, the reviewer sees it before merge — not after production breaks.

Ownership that pages the right person

Every rule gets an owner auto-assigned from git blame on the handler or the authorizing Jira ticket. When a rule drifts, Stoney DMs the owner in Slack with the full forensic trail — or files it back on the original Jira ticket.

Contradiction detection across your rule set

Teams accumulate contradictory rules without realizing it — "Orders must have positive totals" and "Refunds create negative orders inline." Stoney scans your registry, flags the pairs, and lets you triage: keep A, keep B, merge, or reword both.

SOC 2 evidence, generated in one click

Every enforced rule with its authorizing ticket. Every drift event with forensic attribution. Every PR review with its verdict. Auditor-ready CC7.1 and CC8.1 evidence — the parts Vanta and Drata can't produce because they don't read your code.

The Moat

Only Stoney correlates
all three signals.

Every tool in the category reads one signal. Business rules don’t live in any single source — they live in the gap between code, PRs, and tickets. Closing that gap is what makes forensic attribution, pre-merge rule checks, and SOC 2 evidence possible.

Tool	Category	Code	PRs	Tickets	Traffic
Schemathesis	API contract testing	✓
Stainless	SDK generator	✓
Datadog	Observability				✓
Honeycomb	Observability				✓
Linear / Jira	Work tracking			✓
Vanta / Drata	Compliance
Stoney	This product	✓	✓	✓	✓

Nobody else ships forensic attribution, pre-merge rule checks, or CC7.1 / CC8.1 evidence because nobody else has the data to produce them. That’s not a feature gap — it’s an architecture gap.
