The platform

DRIFT doesn't just diff text. It understands your contract — its types, its constraints, its consumers — and tells you what actually breaks.

Semantic contract diffing

Compare API schemas field-by-field with type-aware, breaking-vs-compatible classification. No more guessing what a changed integer means.

Pipeline-native integration

Drop DRIFT into any CI/CD flow — GitHub Actions, GitLab, CircleCI, Jenkins. Gate merges on real contract violations, not vibes.

Zero false positives

Our contract engine understands OpenAPI, gRPC, GraphQL and AsyncAPI. Only true breaking changes surface, tuned by your team.

Sub-second analysis

Rust-powered diffing analyzes 10k-endpoint contracts in under 800ms. Your PRs never wait on the gate.

Visual change previews

Every diff renders as a cinematic, navigable change graph. Reviewers see exactly what moved, renamed, or vanished.

Live drift monitoring

Continuously compare production traffic against your contract. Catch silent drift before an integration breaks.

How it works

DRIFT reads your contract, computes the semantic diff, classifies every change, and gates the merge — all before your coffee cools.

Loved by engineers

“DRIFT caught a breaking response-field rename that would have taken down three downstream services. It paid for itself in one PR.”

Priya Nair

Staff Engineer, Vector

“We replaced a 600-line custom diff script with DRIFT in an afternoon. The visual change graph alone is worth it.”

M

Marcus Lee

Platform Lead, Lumen

“The false-positive rate is genuinely zero. Our team trusts the gate now, which means the gate actually runs.”
