Your AI agents work
while you sleep
The owl works the night shift so you don't have to.
For developers who ship fast and audit everything.
Download for MacI built Zowl because I was tired of babysitting Claude Code. It started as a bash script that queued prompts overnight. Then I added retry logic. Then a pipeline builder. Then I realized — this is a product.
How it works
Three steps to overnight shipping
Build your pipeline
Drag and drop nodes in a visual editor. Define your agent workflow, no YAML, no config files.
Load your tasks
Import tasks from JSON, Markdown, or create them directly in-app. Zowl queues everything for you.
Hit play. Go to bed.
Zowl runs your agents overnight. Wake up to merged PRs, passing tests, and shipped code.
Features
Everything you need to ship overnight
Visual Pipeline Builder
Design your agent workflow visually. Drag-and-drop steps, configure retries, see the full flow at a glance. No YAML, no config files.
Generate from Brief
Paste a project brief and Zowl generates a complete agent pipeline for you, tasks, dependencies, and all.
Multi-Agent Support
Run Claude Code, Codex, or any custom CLI agent. Mix and match agents per step in a single pipeline.
Smart Retries & Recovery
Configure your own retry and recovery strategy per step. Skip, retry, jump to another step, or rewrite the PRD mid-pipeline. You decide what happens when things go wrong.
Import Tasks from PRDs
Already have a PRD? Import your tasks directly into a pipeline. Zowl parses your document and maps each task to an executable step.
PRD Scoring
Get a quality score for your PRD before agents run. Catch ambiguous requirements and improve testability before they waste compute.

Questions & answers
Claude Code, OpenAI Codex, and any CLI-based agent. If it runs in a terminal, Zowl can orchestrate it.
No. Zowl runs 100% locally on your machine. Your code and API keys never leave your computer.
Zowl captures the error context and retries intelligently. You can also configure fallback agents or manual review checkpoints.

You could. But Zowl handles retries, parallelization, logging, and pipeline orchestration — so you can sleep instead of babysit.
Because subscriptions for dev tools are annoying. Pay once, own it forever. Updates included.
