Hyperbrowser scores 66.9 (B) on agent readiness against Skyvern's 63.1 (B), and leads in 2 of 7 scored categories. Skyvern leads on schema & documentation, agent ergonomics, security & auth, maintenance & community and transparency & trust. Both do browser automation. Hyperbrowser accepts x402. Skyvern doesn't.

## Which one, for what

### Hyperbrowser (B)

Good for: Agents that need a cloud browser by the minute plus cheap fetch and search, especially wallet-holding agents with no account.

Ahead on:
- Reliability, 65 against 57
- Payments & pricing, 94 against 32

Also in its favour:
- An agent can pay per call over x402, with no account
- No incidents deducted, where Skyvern loses 3 points for them

Watch for: The official MCP server's last npm release is 1.0.25 of 13 April 2025, and it isn't in the official MCP registry

### 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 68
- Agent ergonomics, 76 against 67
- Security & auth, 59 against 44
- Maintenance & community, 85 against 79
- Transparency & trust, 72 against 64

Also in its favour:
- 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

**Hyperbrowser.** Sessions, Fetch and Search can be bought by x402 at api.hyperbrowser.ai with USDC on Base or Solana and no account, and unit prices are public. The official MCP server was last published in April 2025, no request rate limits or SLA are published, and the privacy notice covers only the website.

**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

### Hyperbrowser

1. With a wallet and no key, POST to https://api.hyperbrowser.ai/x402/session and read the `PAYMENT-REQUIRED` header. Sessions are prepaid for 5 to 60 minutes with no refund
2. Save the x402 creation response. It holds the only copy of the connection tokens, and `managementToken` is what stops the session
3. Stop sessions explicitly in cleanup code. Browser time bills per second until the timeout
4. Use Fetch at $0.001 a page for static pages and keep browser sessions for pages that need interaction
5. Add `&keepAlive=true` to `wsEndpoint` to reconnect after a CDP disconnect. Treat that URL as a secret because it carries the session token

### 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

## Questions

### Which is better for AI agents, Hyperbrowser or Skyvern?
