Comparisons that age gracefully

Dated reviews

Every comparison page shows when the vendor pages were last checked, so stale claims are easier to spot.

Public sources

Source links sit next to the comparison instead of being buried in a private note.

Stable criteria

The core comparison is deployment model, file location, auditability, and workflow fit, not fragile point-in-time feature trivia.

Why teams pick the self-hosted route

Your files stay yours

Processing happens on hardware you control. Nothing is uploaded to a third-party service, which matters when the file is a contract, a medical scan, or unreleased work.

No quotas or per-file fees

The only limit is your machine and your configuration. No third-party per-conversion billing for internal jobs.

One stack, five file types

Image, video, audio, PDF, and files in a single deployment, instead of a separate account for each job.

Open source, auditable

AGPLv3. Your team can read every line, run it air-gapped, and keep it as long as you like.

Run it on your own server

Open source, free forever, and your files never leave your network.
