Drag boxes around an LLM graph until files and APIs become one useful workflow.
licenseMIT
runsyour machine or their cloud
installInstall the Windows/macOS desktop app or a uv/Python package; Docker is available for server deployment.
enginesComponents connect to major LLM providers, local models, vector databases and tool backends.
dataSQLite stores flows, messages and credentials by default; PostgreSQL is optional, and flows export as JSON.
the catch vs GumloopLangflow is more developer-oriented and has a much thinner catalog of general SaaS and browser-automation steps than Gumloop.
setupDesktop installs cleanly, but useful AI flows still require a provider API key or local-model setup; server deployment needs Python/uv or Docker.

why people still pay for Gumloop
People still pay for Gumloop because one automation is easy; maintaining hundreds of connectors and making every run recoverable is the business. The recurring cost buys OAuth review, token refresh, webhooks, polling, schemas, retries, idempotency, queues, secrets, rate limits, observability, and upgrades, not just the visible interface.
