Pomerado - The faster, cheaper, and more reliable alternative to browser use (opens ycombinator.com)
YC startup Pomerado connects agents to any website without needing an API, and it is open source.

YC F26 startup that turns any website into an API or MCP server for agents, with an MIT-licensed open-source core.
Pomerado creates hosted APIs and MCP servers for websites that have none, such as legacy insurance, vendor, logistics and payer portals, EMRs and government sites. Integrations are created from a prompt, hosted with login storage and automatic 2FA, and repaired automatically when a site changes. The company says its deterministic integrations are 2-4x faster, 10-1000x cheaper and 30% more reliable than browser use. It launched on YC Launches on 2026-10-25.
