General

Connects to your repo, reads your .uproject, runs RunUAT BuildCookRun in the cloud for the platform you choose, and gives you back the packaged build. Optionally pushes that build straight into a StreamPixel runtime for pixel streaming.
Same team, two products:
  • StreamPixel is the pixel-streaming runtime that serves your UE app to end users.
  • BuildPixel is the build pipeline that produces the binaries StreamPixel runs.
They work great together — push your code, and a few minutes later your players see the new version. They also work fine independently: BuildPixel works as the build half of any pipeline, and StreamPixel can serve any pre-built UE app.
Yes. Pro is monthly billing, no contracts. Cancel from the dashboard; you stop being charged at the end of your current cycle.

​
Engine and platforms

UE 5.4 (default) and UE 5.3. UE 5.5 is in beta. UE 4.x is not supported.
Yes, on Enterprise. You bring the platform partner status (we can’t grant it). Console SDKs are NDA-gated, so console builds are an Enterprise add-on.
Linux server: yes, included. Use platform: "Linux", buildType: "Server".Android: yes, included.iOS: yes. Requires your Apple Developer account’s signing certs in the repo.
Custom forks are an Enterprise scenario. Talk to enterprise@streampixel.io.

​
Source control

GitHub Actions is a CI runner; we’d be reinventing the entire build pipeline on top of someone else’s runner. The GitHub App lets us own the build pipeline end-to-end while integrating cleanly with GitHub.You can still trigger BuildPixel from a tiny GitHub Action that calls our API — best of both worlds.
Not yet. We’ve focused on GitHub and Perforce because that’s where most UE teams are. Ping us if you’d be a customer if we shipped GitLab or Bitbucket support.
Most common: your .uproject lives more than 3 directories deep in the tree. Set uprojectPath manually on the build setting.

​
Builds

The first build for a new branch is cold — full source clone, cold DDC. Subsequent builds on the same branch are much faster because intermediates and DDC are reused.
The build is marked failed cleanly. You can re-trigger; the next build benefits from any cache that was already warm.
Pro: email/password and magic links.Enterprise: SAML SSO via your identity provider (Okta, Azure AD, Google Workspace). Talk to enterprise@streampixel.io.
