The preflight engine, self-hostable

Lint inspects a PDF against 500+ checks — fonts, color, images, transparency, page geometry, packaging dielines, barcodes — plus a PDF/X-4 conformance suite, and reports exactly what's wrong and where. It never modifies your file. Hosted or self-hostable, with a platform for teams who'd rather not run it themselves.

Print With Synergy

Lint is built byPrint With Synergy, a studio focused on prepress automation and developer tooling for the print and packaging industry. These tools grew out of real plant workflows: extract the facts once, preflight against the standards, measure conformance objectively, and review with prepress-grade tooling.

Every tool — Codex, Lint, Lens, Assay, and the rest of the toolkit — are available for self-hosting or hosted use. Run them on your own infrastructure, adopt a single tool, or use the hosted Print With Synergy service and skip the ops entirely. Lint reads its document facts from Codex, so every check works from the same extracted source of truth.

The hosted service adds multi-tenant auth, Stripe billing with usage-based overage, and quotas — managed hosting around the same open tools.

Two ways to run it

Self-host, or start free on the hosted platform.
