PikoCI — The CI/CD that grows with you
PikoCI · 2026-05-27 · via Show HN

Open Source CI/CD

One binary. Any database. Any queue. Runs anywhere.

Apache 2.0 licensed. Inspired by Concourse CI.

Dogfooding

PikoCI deploys itself.

The pipeline that builds, tests, and deploys PikoCI is publicly visible. PR checks, integration tests against six backends, multi-arch Docker builds, zero-downtime self-redeployment. No account required to view it.

Why PikoCI

What makes it different.

01

Single binary

No Docker Compose. No Kubernetes. No setup scripts. Download and run.

02

Grows with you

Start in memory. Add SQLite for persistence. Add Postgres and distributed workers at scale. The tool never changes.

03

Run pipelines locally

The pipeline is the environment. Run it anywhere. pikoci run -p pipeline.hcl -j test runs any job on your laptop — no server, no push, no waiting. Override resources with local paths. Iterate before touching CI.

04

Five pluggable abstractions

Resource types, runners, services, secret backends, and notification types. Define once, reuse across jobs. Source any of them from a URL.

05

HCL pipelines

Terraform-style syntax. More expressive than YAML. Readable, reviewable, versionable.

06

Truly portable

Bundle the binary with a pipeline file and SQLite. Move it anywhere. Run it instantly.

Define your pipeline

Pipelines as code.

Clean HCL syntax. Resources flow through jobs. Dependencies are explicit. No magic.
