Pure Infrastructure vs Complete Solution
Browserless.io is an excellent service providing cloud Chrome instances. They solve the infrastructure part, but hand the coding problem back to you. Huarp embraces both.
| Feature | Browserless | Huarp |
|---|---|---|
| How to interact? | Via WebSocket (Requires Code Node) | Via Simple API / Native Node |
| Script Writing | You write 100% of Puppeteer | You assemble visual blocks |
| n8n Timeout | Common (long socket connection) | Rare (Async REST API) |
| Session Management | Basic | Managed and Persistent |
| Pricing | Billed by CPU usage | Billed by action success |
The WebSocket Bottleneck
Tools like Browserless require you to keep a WebSocket connection open between n8n and their server. In long or complex workflows, this connection drops frequently, breaking the entire automation.
Huarp uses a REST API architecture. You say "Go to X" and we go. There is no dependency on keeping a fragile socket open.
