Ghostship

Ghostship is an AI-powered quality assurance platform that autonomously detects bugs in your product before they reach users. It integrates natively with GitHub, analyzes pull requests, and simulates real user interactions to surface critical issues with full reproduction steps and code-level context. Backed by Y Combinator (S25), Ghostship helps engineering teams ship faster without sacrificing reliability.

• GitHub-Native Integration: Connect your GitHub repository and provide business logic — Ghostship handles the rest, automatically validating every PR before it merges.
• Autonomous Test Generation: AI agents analyze your product and autonomously generate comprehensive test scenarios based on your app's critical user flows.
• User Flow Simulation: Ghostship crawls your application and simulates real user interactions across any interface, catching bugs the way actual users would encounter them.
• PR-Level Validation: Every pull request is automatically tested with AI-powered validation before code reaches production, preventing regressions at the source.
• Bug Reproduction Steps: When a bug is found, Ghostship delivers step-by-step reproduction instructions, screenshots, and the exact code snippet causing the issue — no guesswork required.
• Relevant Code Chunk Highlighting: Ghostship pinpoints the precise code chunk responsible for each error, accelerating root cause analysis and fixes.
• Real-Time Alerts: Notifications are delivered where your team already works, keeping everyone in the loop the moment agents finish their analysis.
• Speed Without Surprises: By catching issues autonomously before release, teams can scale and ship up to 100x faster while competitors are still debugging.
