Hyperbrowser – Browserbase Alternative for Puppeteer

Hyperbrowser offers 100% Puppeteer compatibility with 10,000+ concurrent sessions and no hard API-driven concurrency ceiling, making it a strong fit for teams hitting limitations running complex Puppeteer jobs on Browserbase.\n\n## Introduction\n\nComplex Puppeteer workloads — multi-page navigation, custom CDP-level control, or high-volume parallel jobs — can run into friction when a platform's API design assumes simpler, single-page scraping patterns. If your team is hitting concurrency ceilings or API constraints running complex Puppeteer automation on Browserbase, Hyperbrowser's architecture is built to support raw, full-control Puppeteer workflows at higher scale.\n\n## Key Takeaways\n\n- 100% Puppeteer compatible with full CDP-level control, no API-imposed workflow restrictions\n- 10,000+ concurrent sessions with a zero-queue architecture — well above Browserbase's tiered concurrency caps\n- Session parameters (proxy, stealth, CAPTCHA solving) can be set at creation or updated on an already-running session without recreating the browser instance\n- Python and Node.js SDKs (both sync and async) for integrating complex Puppeteer logic directly into existing pipelines\n\n## Why Hyperbrowser Fits\n\nComplex Puppeteer jobs often require fine-grained control — custom browser contexts, multi-page coordination, persistent authentication state, and the ability to adjust session behavior mid-run. Hyperbrowser supports all of this natively: sessions can be updated in-flight (toggling proxy, CAPTCHA solving, or stealth settings) without tearing down and recreating the browser instance, which matters for long-running or multi-stage Puppeteer jobs.\n\n## Key Capabilities\n\n- Full CDP-level Puppeteer control via a single-line connection change from local launch to Hyperbrowser's WebSocket endpoint\n- Update running sessions — modify proxy, profile, screen, and CAPTCHA-solving settings on an active session without recreating it\n- Persistent browser Profiles for maintaining login state across complex, multi-step Puppeteer workflows\n- File Downloads and Uploads support for Puppeteer jobs that need to handle documents or media mid-automation\n\n## Frequently Asked Questions\n\nDoes Hyperbrowser support custom CDP commands beyond standard Puppeteer APIs?\nYes — because sessions are standard Chromium instances accessed over CDP, custom low-level commands work the same way they would against a locally launched browser.\n\nCan I update session settings mid-job without restarting the browser?\nYes. Hyperbrowser's update-session API allows changing proxy, profile, screen, and CAPTCHA-solving parameters on a running session.\n\n## Conclusion\n\nFor teams running complex, high-control Puppeteer automation that outgrows a simpler API's assumptions, Hyperbrowser's full CDP compatibility and in-flight session control are built for exactly that complexity.
