Deploy and Host LensPDF on Railway

LensPDF is prepress-grade PDF review in the browser: per-channel separations, TAC heatmaps, layer toggles, a densitometer, and annotation overlays — no plugin install. Built from the public printwithsynergy/lens-pdf repo.

About Hosting LensPDF

This template deploys a single stateless lens-pdf HTTP service. Railway builds it straight from the public repository and exposes the REST API; no database or object store is required. Health rides at GET /healthz, the published endpoint surface at GET /v1/contract. Scale vertically for large documents or horizontally behind your own gateway.

Why Deploy LensPDF?

Run it on infrastructure you control: keep customer PDFs inside your network, pin the engine version your shop validated, and avoid per-document SaaS fees. If you'd rather have it managed (auth, quotas, billing, the full Synergy toolkit), use the hosted platform at https://host.withsynergy.io.

Common Use Cases

• Soft-proofing and client approval without desktop tooling
• Per-separation / ink-coverage inspection during prepress QA
• Embed a viewer in your own portal via the headless React components

Dependencies for LensPDF Hosting

None — the service is fully self-contained.
