Artifacts and limits
Supported artifact types: IPA, APK and AAB.
Upload limit
Each artifact is capped at 2 GiB = 2,147,483,648 bytes.
Workspace capacity
Free: 10 retained + reserved Builds and 1,000,000,000 artifact bytes. Team: unlimited Build count within 25,000,000,000 bytes plus 25,000,000,000 bytes for each active $5/month storage block.
Pending non-expired uploads reserve one Build slot and their declared byte size. Ready/deleting Builds count until the private object is deleted or confirmed absent. Display uses decimal GB; the upload cap remains binary GiB.
Artifacts are private R2 objects. API responses use short-lived access capabilities and never expose the stored object key.
