fline

Connect your coding agent over MCP and it ships your repo. fline writes the Dockerfile and the compose, picks the ports, provisions managed Postgres or Valkey, and hands back a URL already serving. The work happens outside your agent's context, so the deploy does not eat the session you were using to build. Secret values never pass through the agent: it declares the variable names, gets a link, and hands it to you unopened. Private beta, one node, and a maintained list of what does not work.
