Introduction

Blammo is a zero-config deployment testing tool. Push code to GitHub, and Blammo automatically:

1. Clones your repository
2. Detects your framework, database, and ORM
3. Creates a secure ephemeral environment
4. Crawls every route in your app
5. Screenshots each page and diffs against the previous build
6. Reports broken routes, visual changes, and console errors directly on your pull request

Quick start

1. Install the Blammo GitHub App on your repository
2. Push a commit or open a pull request
3. Check your PR for Blammo’s test results

That’s it. No config files, no YAML, no CI changes.

Supported frameworks

Blammo auto-detects and configures environments for:

• Next.js (App Router and Pages Router)
• Nuxt (v3)
• Remix
• SvelteKit
• Astro
• Any framework with a standard npm run build / npm start workflow

What you get

On every push, Blammo posts a comment on your pull request showing you exactly what changed and what broke — with screenshots.
