Lastest
Ship fast, don't break things — AI-recorded visual regression testing with deterministic CI replays.
Lastest is a visual regression testing tool that uses AI to record user flows through a browser and generates deterministic Playwright test code, which CI replays on every commit. Three diff engines (pixel, structural, and perceptual) compare before-and-after screenshots and block merges when unintended UI changes are detected. It is designed for teams shipping fast and for enterprise teams validating vendor-forced releases in ERP and CRM platforms like SAP, Salesforce, Dynamics 365, NetSuite, and Veeva. It can be self-hosted for free or run on Lastest Cloud.

Problem it solves
Teams shipping fast risk unintended UI regressions reaching production, and enterprise teams on vendor-managed platforms like SAP or Salesforce have no reliable, auditable way to prove nothing broke when a forced release lands.
Why people use it
Lastest eliminates the need to write test code manually — AI records flows once, emits deterministic Playwright scripts into your repo, and CI replays them on every commit with three diff engines to catch any visual change. For enterprise release validation, it runs entirely inside the customer's own network, producing timestamped screen-level evidence without any data leaving the perimeter.
Built for
Engineering and QA teams at software companies that ship frequently and need automated UI regression coverage
Also: Enterprise IT and release management teams validating vendor-scheduled ERP/CRM upgrades (SAP, Salesforce, Dynamics 365, NetSuite, Veeva), DevOps engineers integrating regression testing into CI/CD pipelines, Security-conscious teams requiring self-hosted, on-premises test execution
What makes it different
- Zero-token replays: AI is only used at test creation time; every subsequent replay is pure Playwright execution with no ongoing LLM cost
- Three diff engines in one tool: pixelmatch (pixel-perfect), SSIM (structural similarity), and Butteraugli (human-perception-aligned) — runnable individually or together
- Self-hosted by design with FSL-1.1-ALv2 license — screenshots and test code never leave the customer's infrastructure
- Purpose-built release regression mode for vendor-forced ERP/CRM upgrades (SAP S/4HANA, Salesforce, Dynamics 365, NetSuite, Veeva Vault)
- 12 flaky-test guards including timestamp freezing, DOM stability detection, and OCR-aware diffing for deterministic results
