MDisBetter vs Marker — Online Tool vs Open-Source Library
Marker is excellent open-source software — fast, accurate, locally-runnable. MDisBetter is a hosted service. The choice between them is rarely about output quality (both are good) and almost always about whether you want to operate the conversion infrastructure yourself.

Frequently asked questions
When should I pick Marker over MDisBetter?
Three cases: (1) data so sensitive it cannot leave your network even with a BAA, (2) volume so large that GPU economics beat per-page pricing, (3) you need to fork the model and customise behaviour. For everything else, the operational overhead of running Marker yourself dwarfs the cost of using a hosted service.
Are Marker and MDisBetter equally accurate?
On standard digital PDFs, both produce comparable Markdown. Marker has a slight edge on equations (specialised math model). MDisBetter has a slight edge on multi-column reading order and table reconstruction. The differences matter most on edge-case documents.
How fast is Marker compared to MDisBetter?
Marker on a modern GPU runs about 0.5 to 2 seconds per page, once the model weights are loaded and the hardware is yours. MDisBetter converts in the browser with no setup at all, so for a single document you are done before Marker has finished starting. Marker wins when you already own the GPU and process documents continuously.
Does Marker handle OCR?
Yes — Marker includes Surya OCR for scanned PDFs, with quality comparable to commercial OCR engines. MDisBetter's OCR runs server-side on equivalent models. Output quality is similar; setup effort is the differentiator.
Can I use both — Marker for sensitive, MDisBetter for everything else?
Absolutely — and several customers do. Run Marker locally for the small subset of documents that can't leave your network; use MDisBetter for the rest. You get Markdown either way, and whatever you do with it downstream does not care which engine produced it.
