BubbleLab and flowbaker
Both are open-core workflow engines designed to power their respective no-code platforms, making them direct competitors in the agentic workflow builder space.
About BubbleLab
bubblelabai/BubbleLab
Open-core workflow engine powering Bubble Lab — and fully runnable, hostable, and extensible on its own.
Builds workflows as composable TypeScript "Bubbles" (agent/tool primitives) that chain together with automatic execution tracing and observability; includes a local studio UI, CLI scaffolding, and exportable workflow definitions. Targets Slack integration via Pearl AI assistant on the platform side, but the open-core engine itself supports webhook/HTTP triggers and custom integrations with minimal setup—runs entirely on Node.js with built-in Google Gemini support for AI capabilities.
About flowbaker
flowbaker/flowbaker
Execution engine powering Flowbaker, a no code platform to build, connect, and automate workflows.
Built in Go, this locally-deployed executor agent polls the Flowbaker platform for workflow assignments and executes them with native integrations including Discord, GitHub, and Gmail. The agent manages its own lifecycle through simple CLI commands (start, status, reset) and authenticates via workspace-scoped keys generated during setup. It enables decentralized workflow execution while maintaining centralized orchestration through the Flowbaker dashboard.
