Notte: Browser Infrastructure for AI Agents, Explained
Notte is a browser platform for AI agents and web automation. It runs browsers in the cloud with built-in stealth, CAPTCHA solving and proxies, lets developers deploy browser scripts as serverless functions, and keeps credentials and identities out of their code with secret vaults and “personas,” digital identities that come with their own email address and phone number. It also offers an “Anything API” that turns a described task, like pulling details from any Airbnb listing, into a working API endpoint. Notte went through Y Combinator in 2025 and says more than 20,000 developers and 1,000 organizations use it.
The quick answer: Notte is a young, developer-friendly alternative to Browserbase, with low usage pricing and identity tools that let agents create and run their own accounts. In 2026 it removed its own AI agent loop and refocused on infrastructure, so coding agents and other frameworks drive its browsers. Its emphasis on being undetectable is a different philosophy from Browserbase’s verified-identity approach, and worth weighing for your use case. Everything below comes from Notte’s site, pricing, developer summary, GitHub repository and Y Combinator profile.

What Notte does
Notte’s developer summary calls it “a full-stack browser platform for AI agents,” built for “workflows without an API” such as creating accounts, working in logged-in dashboards, submitting forms and collecting data. Its README puts the core simply: “Notte gives AI agents and scripts a reliable browser.”
The main pieces:
- Browser sessions. Hosted browsers that Playwright, Puppeteer or Selenium can drive, with anti-detection, residential proxies and CAPTCHA solving built in, plus session replay for debugging. A local open-source browser uses the same API.
- Browser Functions. Deploy a Python automation and run it on demand, on a schedule or behind an API endpoint, near the browsers for speed. Notte’s homepage calls it “AWS Lambda for browser work.”
- Anything API. Describe a task and Notte builds and deploys it as an endpoint your agent can call, so the agent doesn’t improvise on the site each time.
- Scraping. Extract markdown or structured data from any page into typed models.
Vaults and personas
Notte’s identity tools are its most distinctive feature. Secret Vaults store passwords, MFA tokens and credit cards so agents fetch them at runtime and credentials are “never forwarded to LLMs.” Personas go further: each is a complete digital identity with its own email address and phone number, so an agent can receive one-time codes, pass two-factor checks and verify accounts on its own. Saved browser profiles keep agents logged in across runs.
This is powerful for legitimate automation, such as an agent that manages a company’s vendor portals. It also puts responsibility on the developer, since many sites’ terms restrict automated account creation.
Stealth versus verified identity
Notte markets its browsers as “Undetectable + autosolve,” meaning they’re built to avoid bot detection and solve CAPTCHAs automatically. That’s a common approach in browser automation, and it helps agents work on sites that block bots outright. It differs from Browserbase, which is pushing verified agent identity through the Web Bot Auth standard so agents announce themselves rather than hide. Which approach suits you depends on the sites you automate and your tolerance for the risk that a site changes its rules or blocks you.
What changed in 2026
Notte originally offered its own AI agent that took a goal and navigated sites on its own. In version 1.10, it removed the agent loop and workflows from its SDK, and its developer summary marks the Agents API as deprecated. Notte now positions itself as infrastructure: coding agents like Claude Code, Codex and Cursor drive its browsers through an MCP server, a CLI or an official agent skill that works with more than 30 tools, and reusable tasks become Browser Functions or Anything API endpoints. Teams that built on the old agent API need to migrate.
Pricing
Notte’s pricing combines plan credits with low usage rates:
| Usage | Rate |
|---|---|
| Browser sessions | $0.01 an hour |
| Browser Functions | $0.05 an hour |
| Residential proxies | $10 per GB ($0.20 per GB with your own proxy) |
| AI model tokens | At the provider’s price, with no Notte markup |
| Plan | Price | Includes |
|---|---|---|
| Free | $0 | $10 in credits, granted once with no expiry; 15-minute sessions |
| Developer | $20 a month | $20 in credits a month, 25 concurrent sessions, 120-minute sessions |
| Startup | $100 a month | $100 in credits a month, 100 concurrent sessions, 300-minute sessions |
| Enterprise | Custom | Custom limits, SSO, SLAs and HIPAA |
Notte says core features, including proxies, vaults, personas, sessions and functions, are available on every plan; plans mainly change credits and limits.
The company
Notte Labs is based in San Francisco and was founded in 2025 by Andrea Pinto, its CEO, and Lucas Giordano, its CTO. It went through Y Combinator’s Summer 2025 batch, and its Y Combinator profile lists a team of five. We couldn’t confirm the size of its early funding from a primary source.
Notte’s core framework is source-available under the Server Side Public License (SSPL), which allows free use but places strict conditions on offering it as a hosted service, so it isn’t open source in the traditional sense. Notte also runs BrowserArena, an open benchmark comparing cloud browser providers on speed, reliability and cost, and publishes a comparison of 12 providers’ pricing and features, noting that it competes with the providers listed.
How Notte compares
Notte’s closest competitors are Browserbase, the best-known browser-agent platform, and Browserless, a long-running hosted browser service. Compared with Browserbase, Notte offers lower usage pricing, built-in personas with real email and phone numbers, and the Anything API, while Browserbase has the larger ecosystem, the popular Stagehand framework and a verified-identity strategy. For reading web content rather than acting on it, scraping APIs like Firecrawl and Context.dev are simpler.
Plenty of everyday work never needs a browser agent. Carly connects to thousands of apps directly, so from ChatGPT, Claude or a text message it can update your CRM, book meetings and sort your email without clicking through websites.
Who Notte suits
Notte is a good fit if:
- Your agents need to log in, create accounts or pass two-factor checks on sites without APIs.
- You want cheap per-hour browser sessions and serverless browser functions.
- You want coding agents to drive cloud browsers through MCP or a CLI.
- You’d like to turn a described web task into a reusable API.
Look elsewhere if:
- You want agents to identify themselves to websites rather than avoid detection.
- You need a traditionally open-source license.
- You relied on Notte’s old built-in agent and don’t want to migrate.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
