Prompt management, evaluation, and guardrails for production LLM apps
Build, test, and version prompts in a table-based editor that anyone comfortable with spreadsheets can use.
Add natural-language assertions, pattern matching, or custom code checks and run them over datasets to catch regressions.
Trace every request and response, inspect latency and cost, and diagnose why an LLM answered the way it did.
One-click AI Firewall blocks prompt injection, denial-of-service attempts, and information leaks with customisable content filtering and alerts.
Open-source workflow automation built for AI agents and technical teams
Build automations with a visual node editor, then insert JavaScript or Python code nodes when you need custom logic.
Connect to 500+ native services, any REST API via HTTP nodes, and any agent or coding assistant through MCP.
Run agents alongside regular steps, inspect every decision, and add structured inputs, guardrails and human approval steps.
Watch workflows execute live, open past runs, replay a run with mocked data and re-run just the step that failed.

#1
Unmatched ecosystem of app connectors and reliability, but significantly more expensive and lacks n8n's self-hosting freedom.
#2No-code builder for custom AI agents and workflows
GenAI-native end-to-end QA agent that plans, writes and heals tests in plain language

Free / Open-sourceOutstanding open-source visual canvas for RAG pipelines and LLM agents, but less suited for general API integrations.


SpecialistMultiplayer AI where people and agents work side by side
Turn one prompt into live business apps, AI agents and automated workflows
Powerful visual builder specifically tailored for complex AI agent workflows, but less mature for traditional enterprise automation.

SpecialistDeveloper-first integration platform with granular code control, but lacks n8n's visual node-based workflow builder.

Enterprise-grade security and robust workflow automation, but less focused on open-source self-hosting and consumer use cases.
Free / Open-sourceAn open-source no-code automation tool with a clean interface, but fewer native app integrations than n8n.
