Browserbase vs Northflank

Browserbase scores higher on the AgentReady, 65/100 against 46/100. They differ on 10 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Browserbase. Browserbase is a platform that makes the web as reliable and programmable as APIs, giving AI agents access to cloud browsers, web search, page fetching, sandbox runtime, and major LLMs through a single API key.

Northflank. The runtime platform for AI-native companies.

Where Browserbase is ahead

Browserbase passes llms.txt published, llms-full.txt / full agent docs and mcp discoverable, and Northflank does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference, authentication documented and pricing understandable. Northflank misses those.

And on adopt, free trial or free allowance, official typescript sdk and mcp integration available. Northflank misses those.

Finally, on operate, agent compatibility verified. Northflank misses it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.
