Airtop vs Lightpanda

Airtop

The cloud browser API has a public OpenAPI 3.1 document, Markdown docs, natural-language page calls with a per-call credit cap, and a status page with no incident in the last 90 days. Credit rates for browser time, proxy traffic and AI calls are not published, and the developer changelog's last entry is dated 3 September 2025.

Lightpanda

Version 1.0.2 runs locally with no account, and its 32-tool MCP server has typed schemas, an annotation on every tool and guidance to treat pages as untrusted. Telemetry is on by default, the CDP and HTTP MCP servers have no authentication, the cloud documents its token in the URL, and no status page or cloud terms were found.

Airtop

1. Terminate every session with DELETE /v1/sessions/{id}. Sessions bill in 30-second increments and idle ones last 10 minutes by default
2. Set costThresholdCredits on AI calls and read meta.usage.credits afterwards. Credit rates are not published, so measure them
3. Use page-query with configuration.outputSchema for structured output. prompt-content and summarize-content are deprecated
4. When calling REST without the SDK, poll session status until running before creating a window. Only the SDK waits for you
5. Airtop's integrated proxy cannot reach LinkedIn, ticketing sites and some banks and streaming services. Bring a custom proxy for those

Lightpanda

1. Set LIGHTPANDA_DISABLE_TELEMETRY=true in the server's environment if usage data, the IP address and an instance ID shouldn't leave the machine.
2. Treat text from markdown, html, tree and links as untrusted page content, never as instructions.
3. Pass credentials as $LP_* placeholders in tool arguments and call getEnv without a name; naming a variable returns its value.
4. Check httpStatus in structuredContent after goto, since a 404 page or a load timeout is still reported as a successful navigation.
5. Keep lightpanda serve and lightpanda mcp --port on 127.0.0.1 or a Unix socket; neither checks who connects.
