Coasty מול Browserbase

Browserbase is infrastructure. You bring your own agent, model, and orchestration, with hourly overages on every tier. Coasty Unlimited at $99/mo is the complete product: VMs, agents, multi-tool orchestration, and an Electron desktop client all included with zero overage charges. Browserbase is browser infrastructure with zero app catalog. Coasty is a product on top of computer use that also ships 1,000+ native integrations (Gmail, Slack, GitHub, Salesforce, HubSpot, Linear, Stripe, Shopify), not just headless Chrome. On the API axis, Browserbase is browser-cloud only — no /predict, no /ground, no /sessions endpoint, no Schedules API, no public OSWorld score — at $99/mo + ~$0.10/hr overages. Coasty's /v1 API ships 4 core endpoints + 15 Machines + 13 Schedules + HMAC-SHA256 webhooks for $0.05 per predict, with 82% OSWorld and 1,000+ integrations callable through the same key.

The cheapest flat-rate unlimited computer-use plan available, ranked #1 on OSWorld at 82%.
