Features

Mobile app CI/CD and release management in one place

Mach keeps the mobile release path together instead of scattering builds, store upload, credentials, and test evidence across separate tools.

Build

Artifact

Submit

Cloud builds that stay connected to the rest of release

Run iOS, Android, and Flutter web builds, keep signing assets secure, download artifacts, submit mobile releases to stores, and attach Maestro validation without losing context.

mach build --platform ios

Build runs in cloud

Artifact generated

APK / AAB / IPA ready

mach submit --latest

Store upload tracked

Credentials

Manage certificates, provisioning profiles, keystores, and service credentials from one secure place.

Maestro Tests

Run Maestro flows against your artifacts and keep test results attached to the build history.

Live Dashboard

Follow logs, artifacts, submissions, credentials, and test runs without digging through CI output.

Powerful CLI

Build, submit, manage credentials, and start tests from commands that fit local or CI workflows.

Device Hub

Store Submissions

Submit the latest successful build to App Store Connect or Google Play, then track status beside the build.

Flutter support

Flutter CI/CD for iOS, Android, and web

Use the same CLI and dashboard for Flutter mobile and web builds, signing, versioning, audits, push, deep links, Shorebird OTA, release symbols, artifacts, and mobile store submissions.

Detected and pinned

mach init recognizes Flutter apps and Dart workspaces, then pins the installed stable SDK for repeatable builds.

Profiles without limits

Use any profile names you need, with shared or platform-specific flavors, Dart targets, modes, and environments.

Mobile and web artifacts

Build signed APK, AAB, and IPA artifacts plus deployable Flutter web bundles, with retained release symbols when enabled.

Push, links, and OTA

Wire Mach Push and verified deep links, then ship Dart patches through your own Shorebird account and token.

Profile-driven Flutter builds

Your names, environments, flavors, and targets

Security

Security isn't a feature. It's the foundation.

Your signing keys, secrets, and credentials are protected end-to-end — encrypted at rest, never exposed during builds.

Secrets Encrypted at Rest

All secrets and credentials are stored encrypted. They are never accessible outside of a build.

Expiring Download Links

Build artifacts are served via short-lived links that expire automatically — no permanent public URLs.

Secure Authentication

Every API request is authenticated with short-lived tokens. No long-lived credentials are accepted.

Zero Credential Exposure

Your signing keys are never accessible to the build environment — injected just-in-time and immediately discarded.

Encrypted Vault

Signing keys and provisioning profiles are stored in an encrypted vault, decrypted only when a build runs.

How It Works

Get from install to build, submit, and test

Four steps from zero to a cloud build, then keep the related submissions, credentials, and Maestro results in the dashboard.

Read the setup guide

Install the CLI

Get started with a single npm command.

$ npm install -g @radhya/mach

Authenticate and connect your React Native, Flutter, or Expo React Native project.

$ mach login && mach link

Run a build

Kick off a cloud build for any platform.

$ mach build --platform ios

Monitor in dashboard

View builds, submissions, Maestro test results, artifacts, and credentials from the web.

Dashboard handoff ready

Stack fit

Built for the mobile release path, not generic CI

Mach keeps vanilla React Native, Flutter, and Expo React Native teams close to the work they repeat every week: build the app, sign it safely, submit it, and validate it with Maestro.

Why Mach?

A complete mobile delivery workspace

Mach brings builds, secrets, OTA releases, device installs, submissions, test runs, and delivery status into one workspace.

Build, ship, and update

Managed builders, OTA channels, and store delivery status stay tied to the same release record.

Test on connected devices

Use Install Hub to discover a local test device and push an installable build from the dashboard.

One secure team workspace

Keep credentials and secrets protected while managing member roles and project ownership.

Loved by teams

Don't take our word for it

"Mach cut our CI costs by 60% overnight. We were paying for EAS seats we barely used. Now we pay per build."

Arjun Mehta

CTO, FinTrack

"The security model is what sold us. Our signing keys never touch the build runner — that's a huge deal for compliance."

Sarah Kim

Lead Engineer, Shopify Partner

"One command and the build is running in the cloud. We haven't touched Xcode in weeks."

FAQ

Mobile app CI/CD questions, answered

Ten practical answers on setup, pricing, security, and the full mobile delivery workflow.

Frameworks

Which frameworks does Mach support?

Mach supports Vanilla React Native, Flutter, and Expo React Native projects. Each framework keeps the delivery workflow it needs while builds, credentials, release activity, and history remain in one workspace.

Workspace

What is included in a Mach workspace?

Mach brings together cloud builds, live logs, artifacts, credentials and secrets, OTA releases, connected-device installs, push, store delivery, Maestro testing, project roles, and release history.

Platforms

Can Mach build iOS, Android, and web apps?

Mach runs managed iOS and Android builds for supported projects, and supports Flutter web bundles. The selected framework and build profile determine the targets available for each project.

Getting started

How do I move an existing app to Mach?

Install the CLI, sign in, then initialise or link the project and review the generated mach.config.json. Keep that configuration in version control so your team and CI use the same build profiles.

Pricing

How does Mach pricing work?

The free plan includes 10 Android and 10 iOS builds each month. After that, Android builds are $0.70, iOS builds are $1.20, and managed Maestro testing is $0.40 for the first 15 minutes plus $0.20 for each additional 10-minute block.

OTA delivery

When should I use an OTA release instead of a new build?

Use OTA for compatible JavaScript, styling, and asset changes. Native code, permissions, SDK, or runtime changes still require a new binary; Mach uses channels and runtime compatibility to protect the installed app.

Device installs

Can I install a build directly on a test device?

Yes. Install Hub discovers compatible devices through the local Mach agent and lets you push an installable artifact from the dashboard, without passing files around manually.

Quality & stores

How do testing and store submissions work?

Maestro test runs and store submissions stay attached to the build that produced the artifact, creating a traceable release record. Managed Maestro runs require a Pay as you go wallet.

Security

How does Mach protect signing credentials and secrets?

Mach stores credentials and secrets encrypted at rest, scopes them to the requested build, and keeps sensitive values out of normal dashboard views and build logs.

Teams & AI

Can my team and AI tools access Mach safely?

Project roles control who can work in each workspace, and ownership can be transferred deliberately. Connected MCP apps receive read-only access to allowed project, build, OTA, test, and usage data—not secrets or publishing controls.
