Built by engineers who got tired of guessing.

Why we built this

Product analytics tools show you funnels but not why users dropped off. Error monitors show you stack traces but not what the user was trying to do. Session replay tools are slow, expensive, and creep out your security team.

Observe.js is one snippet that captures every signal — clicks, errors, network requests, performance, and custom events — and stitches them into a single session timeline. So when something breaks, you don't have to guess.

Principles

• 01Fast by default. The SDK is 2 KB and never blocks render. If it slows your site, we failed.
• 02Private by default. Input values are masked. We don't sell or share customer data. Ever.
• 03Honest pricing. Event-based, no per-seat fees. We tell you before you hit a limit.
• 04Open where we can. The SDK is open source. Self-hosting is a first-class option.
