ByteChef: Open-Source API Integration & Workflow Automation Tool

I’ve wasted hours integrating APIs, juggling SaaS apps, and writing code just to move data from one place to another.

One tool gives you webhooks, another only has an API, and suddenly you’re spending an entire afternoon just trying to move some data from A to B.

Meet ByteChef. It’s an open-source automation platform. At first, I thought, “cool, another Zapier clone.” But after playing with it for a bit, it felt more like a dev tool that also happens to be friendly enough for non-devs.

What ByteChef Actually Does

It connects your apps, APIs, and databases so they talk to each other. You can build workflows that run when something happens (like a new payment comes in) or on a schedule (like fetching reports every night). The nice part? You can use it inside your own SaaS product too, so your customers can connect their favorite tools directly without you having to code a million integrations.

A Few Things I Liked

I won’t list every single feature (the docs already do that). Instead, here are the bits that stood out to me:

The UI editor: drag-and-drop style, pretty clean. It’s easy to see how steps connect.
Event-driven + scheduled workflows: I ran one workflow every hour, another one instantly when a webhook fired. Both worked fine.
Code when you need it: This one’s huge. If drag-and-drop feels limiting, you can drop into Python, JS, Ruby, or Java and just write your own logic.

Example: if order.total > 1000:

   discount = order.total * 0.1

else:

   discount = 0

No weird workarounds. Just code.

Developer-friendly touches: things like pushing workflows to Git, exposing them as APIs, or handling authentication automatically. It feels built for people who actually like to code, not just click.
AI-ready: it’s got components to plug in AI models. I didn’t test this deeply, but it looks like you can do stuff like text summarization inside a workflow.

Running It Locally

Getting it running was straightforward. If you’ve got Docker installed, you can be up in minutes. The lazy way (what I did first):

docker compose -f docker-compose.yml up
That starts Postgres + ByteChef together.
If you want more control, you can spin them up separately:
docker network create -d bridge bytechef_network
docker run --name postgres -d -p 5432:5432 \
    --env POSTGRES_USER=postgres \
    --env POSTGRES_PASSWORD=postgres \
    --network bytechef_network \
    postgres:15-alpine
docker run --name bytechef -it -p 8080:8080 \
    --env BYTECHEF_DATASOURCE_URL=jdbc:postgresql://postgres:5432/bytechef \
    --env BYTECHEF_DATASOURCE_USERNAME=postgres \
    --env BYTECHEF_DATASOURCE_PASSWORD=postgres \
    --network bytechef_network \
    docker.bytechef.io/bytechef/bytechef:latest

Then head over to http://localhost:8080/login, create an account, and you’re good to go.

My Takeaway

ByteChef feels like a mix between Zapier and a dev framework. If you’re a non-technical ops person, the drag-and-drop editor is enough. If you’re a developer, you won’t feel boxed in. The fact that it’s open-source and self-hosted is probably the biggest win. No mystery cloud costs. No wondering where your data is. Just something you can run yourself. Would I replace Zapier with it for every tiny thing? Probably not yet — Zapier is still easier for super quick one-off automations. But if I were building a SaaS app that needs customer-facing integrations, or if I wanted serious control over my workflows, ByteChef makes a lot of sense.
