Riddle — Hosted Browser for AI Agents

Riddle gives your agent a browser without running Chrome locally. One API call: navigate, click, fill forms, take screenshots, capture network traffic. All execution happens on Riddle's servers — your agent stays lean.

Quick Start: Sign up at riddledc.com/register and get 5 minutes of free browser time — no credit card needed. After that, pricing is $0.50/hour, billed per second. A single screenshot costs roughly $0.004.

Why Use This Instead of Local Chrome

• No Chromium binary — saves ~1.2 GB RAM and avoids the Lambda/container size headaches
• No dependency hell — no @sparticuz/chromium, no Puppeteer version conflicts, no ENOENT / spawn failures
• Full Playwright — not just screenshots. Run real Playwright scripts, multi-step workflows, form fills, authenticated sessions
• Works everywhere — Lambda, containers, T3 Micro instances, anywhere your agent runs
