Build, sign and ship
artifacts at the speed of the universe
Catalyst is the artifact platform for modern teams. Define a pipeline once, produce reproducible binaries, container images and bundles, then promote them across the universe with full provenance.
Buildable elements: OCI images, web bundles, IPA (React Native) and APK.

The Problems
- Local resources often missing or unavailable for builds
- Frequent connection issues that interrupt your workflows
- Existing cloud solutions are expensive and poorly adapted to your context
- Requires complex setups like iOS development keys that you might not have
- Zero local dependencies— Generate applications in the cloud without needing local iOS dev keys or heavy SDK setups.
- A flawless cloud experience— We analyzed all the flaws of existing cloud CI/CDs and fixed them in Catalyst for a tailored, cost-effective platform.
- Seamless APK and IPA builds— Dedicated support to easily compile, sign, and distribute Android and iOS applications with zero friction.
- Stable, always-available resources— Say goodbye to connection drops and missing resources. Your builds run on our robust, managed infrastructure.
Features
Everything you need to ship artifacts
From source to signed, deployable artifact — in one place. No glue scripts, no guesswork.
Universal artifacts
APK, IPA, OCI images, web bundles, npm/pip packages — one workflow builds every format.
Signed & verified
Every build is signed with cosign and ships with SBOM and SLSA provenance attached.
Reproducible by default
Hermetic builds with content-addressed caching. Same input → same output, guaranteed.
Mobile-first builds
Build Android APK and React Native IPA from one pipeline. Upload to Play Store and TestFlight in one click.
Smart caching
Layer-aware caching cuts repeat builds by up to 80%. Share caches across your entire team.
Promote anywhere
One artifact, many environments. Push to staging, prod, or any registry in a single click.
Web bundles & PWA
Static sites, SPAs and PWAs — bundled, compressed and deployed to edge locations worldwide.
Universal artifacts
APK, IPA, OCI images, web bundles, npm/pip packages — one workflow builds every format.
Pipelines as code
Declarative YAML pipelines with reusable steps, matrix builds and parallel fan-out.
How it works
From commit to artifact in 4 steps
No local setup. No Apple account. No Xcode. Just a repo URL and a pipeline definition.
Connect a repo
GitHub, GitLab or Bitbucket — Catalyst auto-detects your stack and proposes a ready-to-run pipeline.
Define your build
Drop a catalyst.yml or use a template. Matrix builds, parallel jobs and reusable steps included.
Produce artifacts
Each run yields a signed, immutable artifact with SBOM, SLSA provenance and full build logs attached.
Promote & deploy
Promote the exact same artifact across environments. No rebuilds, no surprises.
One file. Every artifact.
Catalyst pipelines are declarative YAML — version-controlled with your code, reviewable in PRs and reusable across projects. No proprietary DSL, no lock-in.
- →Matrix builds across OS and runtime versions
- →Reusable composite steps and shared caches
- →Built-in secrets manager and OIDC for any cloud
- →Run locally with the same engine as production

Builders love Catalyst
From solo developers to enterprise engineering teams.
“Catalyst streamlined our artifact production and made unsigned mobile IPA builds seamless and reliable. The easy checkout and subscription options made payment simple so we could scale fast.”
NAVIDPAD
Engineering Team — NAVIDPAD
“I built a cloud tool to produce iOS IPA and Android APK without a Mac. Catalyst lets you connect a repo, choose a platform, and get APK/IPA/web bundles with a free plan and no credit card.”
Beyas Ambroise BEKONO
Lead dev fullstack
“Catalyst lets us implicitly centralize artifact production and manage our Expo mobile dev team from one place. We ship without massive resources, and even our Flutter apps are built reliably.”
