Move fast and break things.
Zero-config deployment testing for teams that move fast. We'll help you catch the broken things before your users do.

How it works
Three steps. Zero config. Works with any framework.
Install the GitHub App
One click to connect your repos. No config files, no YAML, no CI changes.
Push your code
Blammo automatically clones your repo, detects your framework, and spins up an ephemeral environment.
See what broke
Get a PR comment with broken routes, visual diffs, console errors, and interactive test results.
Your tests pass.
Your users disagree.
You know the drill. You build the perfect test environment — seeded database, warm caches, migrations already run. Every test passes. Then a real user signs up with a fresh account and nothing works.
Blammo tests your app the way your users experience it. Every build gets a brand new environment — cold start, empty database, no leftover state. If it breaks from zero, you'll know before they do.
Ephemeral by default. Spun up per commit. Torn down when done.
// Your test environment
✓ Database seeded with test data
✓ Migrations ran last Tuesday
✓ Redis cache warm from last run
✓ Admin user already exists
All 47 tests passing!
// Blammo's environment
▸ Fresh container from scratch
▸ Empty database, migrations applied
▸ No cache, no state, no shortcuts
▸ First-time user experience
✗ /onboarding 500 — missing seed data
✗ /dashboard blank page — no default workspace
Everything you need to ship with confidence
Blammo handles the boring parts of deployment testing so you can focus on building.
Zero config
Auto-detects Next.js, Nuxt, Remix, SvelteKit, Astro, and more. Database and ORM detection included.
LLM-powered
Claude fallback for unknown frameworks. Analyzes build errors, discovers routes, and identifies technologies.
Screenshot evidence
Every broken route gets a screenshot so you can see exactly what your users would see. No guessing from stack traces.
Interactive exploration
AI-driven click-through testing discovers broken forms, dead links, and JS errors automatically.
Fresh environments, every time
No warm caches, no seeded data, no 'works on my machine.' Every build starts from absolute zero — just like your users experience it.
Multi-VCS
Works with GitHub, GitLab, and Bitbucket. Same experience across all your repos.
Move fast. Break nothing.
Early users are already shipping with more confidence.
"I pushed a CSS change that broke checkout on mobile. Blammo caught it before my users did."

"Finally, deployment testing that doesn't require a PhD in CI/CD. Install the app, push code, done."
Sam R.
Frontend developer
"The visual diffs alone are worth it. But the interactive testing? That's magic."
