Sideflap turns API-less apps into MCP tools

Editorial interest 82/100 Selection signal · not a rating of the site

Sideflap presents a cloud browser and self-hosted option for exposing apps without APIs as tools for AI agents.

Landing page captured for the 2026-11-04 issue.

For: People automating work in apps without APIs
Worth noticing: The page labels its browser-versus-tool comparison a simulation, not a benchmark.

Field notes

The page shows a Skool example with separate tools for listing posts, drafting replies, and replying, and marks the reply action as requiring approval. It also presents a Fresha appointment-change example as a single tool call, while explicitly cautioning that the comparison with browser automation is a simulation rather than a benchmark. Definitions are described as readable files that users can fork or fix.
