Preview environments for every pull request
Every branch gets its own isolated environment, with your full stack, services, and data, automatically. No setup. No shared staging conflicts.
Built for teams who ship continuously
Upsun connects to your Git workflow and provisions a full-stack environment for every branch or pull request automatically. Code, databases, and services included. Test in production-like conditions before anything ships.
Staging conflicts
Multiple features competing for the same environment delay reviews and create coordination overhead.
Environment drift
Shared staging diverges from production over time, so issues caught there may not reflect what actually happens in production.
Manual setup overhead
Spinning up a test environment means writing scripts, coordinating with platform teams, or waiting. Upsun removes that work entirely.
Uncertain deployments
When you cannot test against a real stack before releasing, you ship with less confidence.
From pull request to environment in seconds
Open a branch or pull request
Upsun detects the new branch from your connected Git repository. Each update triggers a rebuild so previews stay aligned with code changes.
Your full stack is provisioned automatically
The platform clones your application, services, databases, and infrastructure configuration into a dedicated environment. No scripts. No manual steps.
Review, test, and share
Developers, QA, and stakeholders get a live URL. Test independently. Share with anyone. When a branch is no longer active, Upsun pauses the environment automatically.
Everything your team needs to review with confidence
Upsun provisions complete environments, not just app containers. Your databases, caches, queues, and background workers are all there. What your team tests is what your users will see.
Automatic environment creation
Every branch and pull request gets its own environment, provisioned the moment a branch is pushed.
Full-stack cloning
Code, configuration, databases, caches, queues, and services are cloned together. No partial environments.
Git-native workflow
Upsun works directly with your existing Git workflow. No new tools. No new processes.
Complete environment isolation
Each branch runs independently. Changes in one environment cannot impact production or any other preview.
Production-like infrastructure
Environments are configured from the same infrastructure-as-code file as production. What you test is what you ship.
Safe data handling
Tunnel into preview databases to test migrations. Configure sanitization scripts in your deploy hook to automatically scrub PII from every cloned environment. No manual data copying.
What teams use preview environments for
Pull request validation
Every PR gets a live environment. Reviewers can test the change directly, not just read the diff.
Database migrations
Validate schema changes against a production-grade dataset before they go anywhere near production.
QA and stakeholder sign-off
Share a branch URL with QA teams or non-technical stakeholders. No staging access required.
Parallel feature development
Multiple teams ship simultaneously without fighting over a shared environment.
This morning, we launched a new development environment to test a disruptive feature. That would've been a huge ordeal in our old setup. Now it's just part of the workflow.
