Open-source Swimlane alternatives

StackStorm is an open-source platform that connects the tools in your infrastructure and runs automated actions when events occur. Nicknamed 'IFTTT for Ops', it targets DevOps and site reliability teams who want to automate remediation, incident response, troubleshooting and deployments instead of handling every alert by hand.

It combines a rules engine that matches incoming events, workflows that chain several actions together, and ChatOps so operators can trigger and follow automation from chat. A catalog of integration packs, about 160 according to the project description, supplies more than 6,000 ready-made actions for common tools, and you can add your own. The project provides an installer script for a clean 64-bit Linux server.

StackStorm is Apache-2.0 licensed software that you run on your own Linux hosts. It suits operations teams building event-driven runbooks who prefer to self-host, and community help is available through a forum and a Slack group.

Tracecat is open-source software for automating security operations, used by teams and AI agents together. It aims to give security teams everything they need to build agents and automate cyber defense in one place, from alert handling to incident response, with unlimited agents, cases, lookup tables and workflows.

Its building blocks include agents and skills built from prompts, tools and MCP, case management for tracking and resolving incidents with agent help, workflows that execute deterministic logic with resilience on Temporal, tables for storing and querying structured data, and a Tracecat MCP that turns prompts into automations from Claude Code, Codex and similar tools. The stack is Python with FastAPI and a Next.js interface.

Tracecat is licensed under AGPL-3.0 and can be self-hosted, with a managed cloud also offered by the vendor. It suits security operations, detection engineering and incident response teams that want a programmable, AI-ready alternative to proprietary SOAR tools.
