01 / PREPARE
Reusable test packages
Package endpoints, variables, headers, bodies and assertions into a test flow people — and agents — can repeat.
Windows · .NET 10 · local-first
API testing,
with a memory.
Prepare a reusable test package. Sign in. Run one case at a time. Keep the evidence. E2E Tester turns exploratory API work into a reliable, reviewable trail.
Current release: 0.8.6 · Requires the .NET 10 Desktop Runtime · Microsoft Edge WebView2 is needed for Swagger sign-in.
Evidence-first, not request-firstA calmer way to test
Explore safely. Keep what mattered.
Packages carry instructions, defaults, assertions and editable cases. Nothing is sent just by opening a package.
02 / RUN
Guided variations
Run one case at a time. Edit safely, add a variation when needed, and distinguish PASS, FAIL and INCONCLUSIVE.
03 / PROVE
Evidence that travels
Export JSON or HTML reports, redacted cURL and evidence bundles for a teammate, a ticket, or your next self.
Built for real environments
From Swagger sign-in to database verification.
Identity-aware
Use remembered browser sessions, JWT/API tokens, OIDC/PKCE and named identities without turning a test run into a credential hunt.
Deep when required
Optional SQL Server, MySQL, PostgreSQL and SQLite fixtures and verification give a request its real-world context.
Agent-ready
Ship MCP stdio tools and structured reports alongside local-first workspace recovery, backups and saved runs.
Updates & rollback
Versioned updates, on your terms.
E2E Tester uses Velopack’s static update feed. Keep an older full package installed or select an earlier release when you need to roll back.
