Zyk

Durable workflows built by Claude Code, run on Hatchet. No drag-and-drop. Zyk Core (free) + Zyk Pro.

@hatchet_dev Built this with @zykdev. Slack interaction webhook resumes a durably paused Hatchet workflow. Workflow posts buttons, user clicks, ctx.waitForEvent() resumes, workflow continues. Claude builds it from plain English.

Good question. It's fully blocking. The workflow pauses durably until a human approves or rejects it.

Zyk uses Hatchet under the hood so the pause survives server restarts and can wait hours or days. State is persisted in Postgres.

Human input can be completed via the Zyk task UI, Slack, or any channel you configure.
You can also set a timeout with a default action if no one responds.

Nothing executes until you decide.

AI agents that act without asking first are a liability.

Built Zyk. Describe any workflow in a sentence, Claude generates it, Hatchet runs it durably.

This one searches competitor news every Monday, drafts a message, and waits for human approval before anything reaches the team.

Open source. One-click Railway deploy.

Stack if anyone's curious:

Claude Desktop → creates and updates workflows
Zyk → MCP server that deploys it to Hatchet
Hatchet → durable execution engine with full traceability, retries etc.
Slack → human approval gate
Railway → one-click deploy

Zyk alpha is live🎉

Claude is the interface. Build, deploy, and manage workflows without ever leaving it. Retries, scheduling, and human approval are all built in. Zyk UI handles diagrams, task list, and run history.

Deployed on Railway in under 10 minutes. The GitHub issue triage example is a good starting point.

Drop feedback here or open an issue, both welcome.

Workflow automation built around Claude, not bolted onto it.
Create and manage workflows directly in Claude. Self-host in minutes on Railway.
Alpha coming soon. https://t.co/HeaqVLJ4Nj

The workflow:
Fetch all Star Wars films directed by George Lucas from the SWAPI API.

For each film:
- Ask me if I like the film
- Wait up to 1 minute for my answer
- If I don't answer, assume "no"
- Log the decision

At the end:
- Summarize all my decisions

I tried building this workflow with n8n's AI assistant.
It failed.
Same prompt with Zyk. Worked in one shot.

Small note: this is an early preview of Zyk. The playground shows the core concept, the actual product runs as an MCP server inside Claude. Feedback welcome!

Describe a workflow, AI writes and runs it with retries, scheduling, and human-in-the-loop built in on @hatchet_dev. Here's an incident response workflow live demo:
