Trove
Content-addressed · versioned · API-first

The asset store for print & prepress.

Trove versions, organizes, and serves every artwork, die, font, profile, and proof in one content-addressed store — a single source of assets for the prepress tools you already run. API-first, dedup by default, hosted or self-host.

AGPL-3.0 · content-addressed dedup · immutable versions · feeds your prepress tools

How it works

From upload to a versioned source of truth

Trove keeps every asset content-addressed and immutable, then serves it to your prepress tools by hash — so extraction, preflight, imposition, and production all read the exact same bytes.

01

Ingest

Push artwork, dies, fonts, ICC profiles, and proofs over REST. Trove hashes every byte on the way in — identical assets collapse to one stored object.

02

Version

Each upload is an immutable, content-addressed version. Nothing is overwritten; every revision is reachable by its SHA, so history is the default, not an add-on.

03

Organize

Tag, group by job or SKU, and attach metadata. Search across the whole store by kind, fingerprint, or attribute — find the right die or font in seconds.

04

Serve your tools

codex extracts, lint preflights, sift plans, compile produces, lens reviews — each reads its inputs straight from Trove by content hash. One source of assets.

Everything a prepress asset store needs

Built for web-to-print platforms, packaging houses, and prepress teams that need one trustworthy home for every production asset — without lock-in.

Content-addressed dedup

Every asset is keyed by SHA-256. Re-upload the same artwork from ten jobs and Trove stores it once — storage stays lean and identity is exact, not filename-guessed.

Immutable versioning

Uploads never overwrite. Each revision is its own content-addressed object, so full history is always reachable and an approved proof can never silently change.

Metadata & search

Tag by job, SKU, customer, or asset kind; attach arbitrary metadata. Query the whole store by fingerprint, kind, or attribute to find the right die, font, or profile fast.

Feeds your prepress tools

codex, lint, sift, compile, and lens can each read inputs from Trove by content hash — one canonical store of artwork, dies, fonts, ICC profiles, and proofs.

Tenant-scoped & access-controlled

Assets live behind per-tenant isolation with role-based access. The hosted platform adds auth, quotas, and audit — your store, your boundaries.

Self-host or hosted

AGPL-3.0 OSS you can run on Docker or Railway with your own S3/R2 bucket, or use managed Print With Synergy hosting — same store, managed and metered.

Hybrid by design

Cloud convenience, on-prem control

Packaging houses and regulated prepress can't always put masters in the cloud. Trove lets the bytes of record stay on-site while the hosted service still gives you versioning, search, and a store that reads by hash.

On-prem origin, cloud cache

Keep masters on the plant floor and let Trove cache hot copies in the cloud for speed. Per-asset placement policy — cloud-only, on-prem origin + cloud cache, mirror, or stub-only — decides where the bytes of record live.

On-prem agent, no inbound ports

A single static daemon dials out to Trove over one persistent control channel — nothing to expose. File bytes move agent↔R2 over short-lived presigned URLs, never over the control socket, and every transfer is hash-verified end to end.

Right-to-erasure, built in

GDPR erase is a first-class operation: purge a blob's stored bytes and its cached derived facts on request. Content-addressed dedup means erase only ever removes truly unreferenced content — never bytes another job still relies on.

Zero-knowledge encryption

Optional per-tenant client-side encryption: the on-prem agent envelope-encrypts before bytes ever leave your network, so the cloud holds only ciphertext and Trove never sees plaintext or your keys. Dedup still works — it's keyed on the plaintext hash.

Pricing

Simple, usage-ready pricing

Run the asset store as a managed hosted service, or self-host the open source — same store, you pick who runs it.
