Neon Object Storage
This is a preview feature and only available in us-east-2. Neon Object Storage is S3-compatible object storage that branches with your projects: every branch gets its own isolated storage state, so files and database rows stay in sync across dev, preview, staging, and production.
Use this skill to help the user store and serve files that branch alongside their database. Deliver a working bucket and upload/download flow, a branch-aware S3 client wired to the injected env vars, or a precise answer from the official Neon docs.
When to Use
Reach for Neon Object Storage when the user needs to store files (images, uploads, generated assets, documents, backups) and any of the following are true:
- They already use Neon Postgres and don't want a second provider. One backend, one bill, one CLI, one set of branches — instead of standing up and wiring a separate AWS S3 / R2 / Supabase Storage account. The same Neon credential that backs the database backs storage.
- Files must stay in sync with the database across environments. Storage branches together with your Postgres data. Fork a branch and the child instantly inherits the parent's buckets and objects at that point in time — copy-on-write, so no data is duplicated. This is what makes agent, dev, preview, and test environments seamless: a preview branch gets a consistent snapshot of both the rows and the files they reference, and writes on the child never touch the parent.
- They want safe, throwaway environments. Upload, overwrite, and delete files in a preview/CI branch without any risk to production data, then drop the branch.
- They want standard S3 tooling. It's built on S3 semantics and speaks the S3 API, so the AWS SDKs,
boto3, the AWS CLI, and presigned URLs all work — reliable and familiar, with no proprietary client.
If the user has no Neon project, isn't on Postgres, and just needs a standalone CDN-backed asset store, a dedicated object store may fit better — but the moment branch-consistent files + rows matter, this is the reason to use it.
