Notte
Cloud browser sessions at $0.01 per hour with stealth, proxies, profiles, secret vaults and personas, a hosted MCP server and serverless browser functions; SSPL-licensed core. A low-cost browser cloud whose identity and credential tooling stands out, with isolation left undocumented.
Overview
Notte is a browser platform for AI agents from Notte Labs, a Y Combinator W25 company. Cloud sessions are isolated browser instances with anti-detection, proxies and captcha solving built in; you attach Playwright over the session's CDP URL, use the notte-sdk Python or Node packages, the Homebrew CLI, or the hosted MCP server at api.notte.cc/mcp, which exposes browser observe, action, scrape, file and profile tools. The docs do not say what sits beneath a session. Browser Functions deploy automations as serverless endpoints with cron scheduling.
Sessions default to 15 minutes with plan caps up to 5 hours on Startup; profiles persist cookies and storage, vaults keep credentials out of model context and personas supply email, phone and 2FA identities. Browser time is $0.01 per hour on top of monthly credit plans from $0 to $100. The core repository is open under SSPL-1.0 (local Playwright sessions and scraping), while stealth sessions, functions, vaults and personas are hosted only. SOC 2 Type II is stated, with HIPAA and on-premise on Enterprise.
Notable
- Y Combinator W25; SOC 2 Type II stated on the homepage
- Core repository licensed SSPL-1.0 with 2.1k GitHub stars
- Maintains BrowserArena, an open-source benchmark comparing cloud browser providers
Notte specifications
| Attribute | Details |
|---|---|
| Isolation | Sessions are described as isolated browser instances running in the cloud; the container or VM boundary is not named |
| Deployment | Hosted platform |
| Open source | Yes (SSPL-1.0) |
| SDKs and interfaces | Python, JavaScript/TypeScript, CLI, REST API, MCP server |
| Cold start (vendor claim) | Not documented |
| Max session length | max_duration_minutes defaults to 15 (API maximum 1,440) with an idle timeout of 3 minutes (max 30); plan caps are 15 minutes (Free), 120 minutes (Developer), 300 minutes (Startup), custom (Enterprise) |
| Persistence | Profiles snapshot cookies, local storage and session storage (not cache, history or extensions) and reload with persist true/false; vaults hold credentials that are never forwarded to LLMs; personas provide email, phone and 2FA identities |
| GPU | No — not offered |
| Networking | Residential proxies at $10/GB, bring your own at $0.20/GB on Startup; captcha solving and anti-detection; secret proxies keep real credential values away from the browser |
| Pricing | Browser sessions $0.01 per hour; browser functions $0.05 per hour; residential proxy $10/GB; LLM tokens at cost. Free $0: $10 one-time credits, 5 concurrent, 15-minute sessions. Developer $20/month: $20 credits, 25 concurrent, 120-minute sessions. Startup $100/month: $100 credits, 100 concurrent, 300-minute sessions, BYO keys and proxy. Enterprise: custom, SSO, SLAs, HIPAA, on-premise |
| Free tier | Free plan: $10 credits granted once with no expiry, 5 concurrent browsers, 15-minute sessions, 5 vaults and 5 personas |
| Compliance | SOC 2 Type II; HIPAA and on-premise deployment on Enterprise |
| Regions | Not documented |

Strengths and trade-offs
Strengths
- You want the lowest listed browser-hour price with a no-expiry free credit
- You need vaults and personas for sign-ups, logins and 2FA
- You want a hosted MCP server with profiles and auth tools
- You want to schedule automations as serverless browser functions
Trade-offs
- Isolation boundary and regions are not documented
- Free and Developer sessions cap at 15 and 120 minutes
- SSPL licence on the open-source core; the cloud features are not self-hostable below Enterprise
- The legacy Agents API is deprecated, so the agent story is in transition
Good fit for: Agents that need cheap browser sessions with credential vaults and synthetic identities for sign-ups and logins.
