Which one, for what

Notte B

Good for Teams that want hosted browsers together with agents, vaults for logins, personas with mailboxes and scheduled browser functions behind one key.

Ahead on

  • Payments & pricing, 40 against 32

Also in its favour

  • No incidents deducted, where Skyvern loses 3 points for them

Watch for

status.notte.cc shows the Scrape API down on 15 of 90 days (about 6 hours in total) and CAPTCHA solving at 88.9 per cent availability

Skyvern B

Good for Agents that must finish a multi-step job on sites with logins, 2FA and forms, where stored credentials, saved workflows and cached scripts matter more than raw browser time.

Ahead on

  • Schema & documentation, 88 against 74
  • Transparency & trust, 72 against 61

Also in its favour

  • Runs on your own machine
  • Open source

Watch for

Every API key and OAuth token has full organisation authority. The docs state there are no read-only, per-endpoint or per-resource keys

Verdicts

Notte

Notte publishes an OpenAPI 3.1 contract for 100 operations, a hosted MCP server with eight tools and OAuth, and a free plan with $10 of credits and no card. Its status page records about six hours of Scrape API downtime in 90 days, and a bot check blocked our read of the terms and privacy policy.

Skyvern

The hosted MCP server annotates every tool as read-only or destructive and can advertise a 29 or 32-tool subset in place of 114, and the API has a written six-month deprecation policy. Every key and OAuth token carries full organisation authority, with no read-only or scoped credential, and no request rate limits are documented.

Before you call either

Notte

  1. Send Authorization: Bearer $NOTTE_API_KEY to https://api.notte.cc. A person creates the key in the console at console.notte.cc first
  2. Stop every session when the task ends. Sessions close after 3 idle minutes or 15 minutes in total by default, and the Free plan caps a session at 15 minutes
  3. Use https://api.notte.cc/mcp for browser work. Function and agent administration tools are only on https://api.notte.cc/mcp/full
  4. Back off on 429 and on 529, which means the cluster has too many sessions. The SDKs do not retry rate limits for you
  5. Download session replays within 24 hours. The recordings page says they are deleted after that

Skyvern

  1. Connect to https://api.skyvern.com/mcp/x/lean or /x/operate, or send X-Skyvern-Scope, so the client loads 32 or 29 tools. The scope filters the list and does not limit permissions
  2. Use a separate Skyvern organisation for each blast radius. Any key or OAuth token can read and write stored credentials and delete workflows
  3. Never pass passwords to skyvern_act or skyvern_type. Store them as credentials and call skyvern_login
  4. Set max_steps on tasks, or x-max-steps-override on agent runs, to cap credits. A run that reaches the cap ends as timed_out
  5. On 503 from POST /v1/run/agents, wait Retry-After seconds. No run was created, so resubmitting is safe

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
