Epsilon has put natural-language interface testing into production across multiple teams using Amazon Nova Act and managed AWS browsers, AWS says. Epsilon's internal benchmarks show a representative 18-step workflow took 5-10 minutes to author, compared with 30-90 minutes for an equivalent Playwright script.

Teams submit plain-English steps through a shared platform API. Tests run in isolated browser sessions under scoped roles in each team's AWS account, with screenshots and results stored for review. Epsilon retains Playwright as its regression-testing backbone. Its reported 100 percent replay pass rate applies to saved successful workflows after an initial exploration phase that typically requires 4-5 prompt iterations.
