Open-source engines · hosted or self-host

The PDF workflow platform for print & prepress.

Extract, preflight, impose, trap, and review PDFs through one API-first workflow engine. Chain the whole Print With Synergy stack into automated, replayable pipelines — run it hosted, or self-host the open source.

How it works

One workflow engine, the whole prepress pipeline

Synergy chains the engines into versioned, replayable DAG workflows — submit a job over REST, stream results over SSE.

Upload & extract

codex-pdf turns every file into normalized facts — fonts, color, images, dielines, barcodes — the source of truth the rest of the stack reads.

Preflight & decide

lint-pdf runs 500+ checks plus a PDF/X-4 conformance suite, emitting located findings you can gate workflows on.

Produce

compile-pdf rewrites, adds marks, imposes, and traps — deterministic, audit-logged PDF output with SHA-256 lineage.

Review & ship

lens-pdf renders separations, TAC, and overlays for human review; synergy orchestrates the whole DAG via REST + SSE.

Everything a PDF workflow needs

Built for web-to-print platforms, packaging houses, and prepress teams that demand precision without lock-in.

API-first workflows

Submit a DAG job over REST, stream progress over SSE. Versioned, immutable, replayable workflows with dry-run and run comparison.

Single extraction layer

codex-pdf extracts every PDF fact once — fonts, color, images, OCGs, dielines, barcodes — and the whole stack reads from it. No double work.

500+ preflight checks

lint-pdf inspects against 500+ checks plus a PDF/X-4 conformance suite (ISO 15930-7), GWG profiles, and bring-your-own PitStop/callas imports.

Deterministic production

compile-pdf rewrites, marks, imposes, and traps — byte-deterministic output with SHA-256 lineage so every transform is reproducible and auditable.

Prepress-grade viewer

lens-pdf renders per-channel separations, TAC heatmaps, layer toggles, a densitometer, and annotation overlays — embeddable in any host.

Self-host or hosted

Every engine is AGPL-3.0 OSS you can run on Docker Compose or Railway. Or skip ops entirely with the hosted SaaS — same engines, managed.

Open source

One stack. Independent engines. Self-host any or all of it.

Every engine is a standalone, AGPL-3.0 service with its own REST contract. Synergy chains them into workflows — adopt one engine, or run the whole stack on your own infrastructure with no SaaS dependency.
