Bubble Lab

Bubble Lab is an open-core, agentic workflow automation platform built for developers. Its open-source (Apache-2.0) TypeScript engine lets you compose AI agents and integrations as typed, composable units called "Bubbles" — service bubbles (Slack, Gmail, PostgreSQL, Google Sheets, Airtable, ElevenLabs, Resend, and more) and tool bubbles (web scraping, research agents, SQL, LinkedIn, Reddit, YouTube) — then stitches them into production-grade "BubbleFlow" pipelines with end-to-end type safety, built-in logging, tracing, and step-level observability. Workflows are fully runnable, self-hostable, and exportable to your own backend, or authored visually in the hosted Bubble Studio. Scaffold a project in seconds with the create-bubblelab-app CLI. Backed by Y Combinator (W26).

Bubble Lab is profiled on the APIs.io network. Tagged areas include Workflow-Automation, AI Agents, Agentic Workflows, Integration, and Developer Tools.

Bubble Lab’s developer surface includes documentation, API reference, getting-started guide, signup flow, support, CLI, and 13 more developer resources.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 90 points between them, because the conditional facet above carries the other 10. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 90% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/bubble-lab: open an issue to ask a question, or submit a pull request to add artifacts.
