Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on visual node-based workflow editor, and large library of pre-built integrations caught me off guard. still, I'd recommend giving it a real trial.

I've evaluated a lot of these over the years. What stands out here is hundreds of app and API integrations — handled better than most — and combines visual building with custom code. Worth the time if this is your use case.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on hundreds of app and API integrations, and strong support for AI agents and LLM workflows caught me off guard. Some advanced features gated behind paid plans is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Use it every day

Honestly didn't expect to like it this much. Hundreds of app and API integrations is exactly what I needed, and large library of pre-built integrations. I do wish self-hosting requires technical setup, but I reach for it almost every day now and it just clicks.
