Lastest Demo — Record, Test, Diff, Approve

## The Problem Visual regression testing is either **expensive**, **flaky**, or **painful to maintain**. - **Cloud tools**: per-screenshot pricing, cloud-only, no self-hosting - **Enterprise tools**: steep learning curve, locked to specific frameworks - **Open-source tools**: free but no dashboard, no collaboration, no AI, or in maintenance mode Meanwhile, you just need to know: **"Did my last commit break the UI?"** ## The Solution Lastest is a free, self-hosted visual regression testing platform that **records your tests, writes them with AI, runs them anywhere, and fixes them when they break** — all in one tool. ``` 1. Point it at your app 2. Record your user flows (point-and-click, no code) 3. AI generates resilient test code with multi-selector fallback 4. Run locally, on remote runners, or in an embedded browser container 5. Screenshots compared with 3 diff engines (pixelmatch, SSIM, Butteraugli) 6. Review and approve visual changes — or let AI auto-classify them ``` Your data stays on your server. Your screenshots never leave your infra. It costs $0 forever. --- ## Three Ways to Work Lastest adapts to how you want to build tests — from fully manual to fully autonomous. ### 1. AI-Free (Manual Recording) Open the recorder, click through your app, hit stop. Lastest captures every interaction and generates deterministic Playwright code — no AI involved, no API keys needed. You own the test code and can edit it by hand. **Best for:** Teams that don't want AI, air-gapped environments, simple flows. ### 2. AI-Assisted (Human-in-the-Loop) AI generates, fixes, or enhances tests — but you review and approve before anything is saved. Feed it a URL and get a test back. Import OpenAPI specs or user stories and AI extracts test cases. When a test breaks, AI proposes a fix and you decide whether to accept it. **Best for:** Day-to-day development, iterating on tests, fixing breakages fast. ### 3. Full Autonomous (P
