Docling vs Promptfoo
A side-by-side editorial comparison of Docling and Promptfoo — release velocity, themes, recent moves, and the top alternatives to consider.
Docling vs Promptfoo: at a glance
What is Docling?
Docling now swaps broken PDF text layers for OCR and limits what hostile files can consume
Docling keeps releasing every few days, and late October brought three kinds of change. Quality: broken PDF text layers are replaced with OCR, RapidOCR detects page orientation, and a heading style signal runs without generating parsed pages. Reach: mixed-format ZIP inputs and transformers and MLX presets for the ASR pipelines. Safety: 2.142.1 limits decompressed archive members and decoded image pixels, bounds several parsers, and requires trusted input for Tectonic TikZ rendering.
What is Promptfoo?
Promptfoo's feed has gone quiet except for small fixes to its code-scan action.
The newest entries are code-scan GitHub Action patches: 0.2.1 updates type definitions and 0.2.2 mints the OIDC token after the CLI installs. The main evaluator's last visible release, 0.121.20 in July, added Claude Opus 5, Kimi K3 and websocket URL templating, following a run of releases that tracked each new frontier model.

◆ Current state
Docling keeps releasing every few days, and late October brought three kinds of change. Quality: broken PDF text layers are replaced with OCR, RapidOCR detects page orientation, and a heading style signal runs without generating parsed pages. Reach: mixed-format ZIP inputs and transformers and MLX presets for the ASR pipelines. Safety: 2.142.1 limits decompressed archive members and decoded image pixels, bounds several parsers, and requires trusted input for Tectonic TikZ rendering.
◆ Where it's heading
As the format list has filled out, the work has turned to what happens when input is bad or malicious. The 2.142.1 hardening set reads like a response to treating documents as untrusted input, and it sits beside bounds on untrusted model output. Speech is also becoming a real pipeline, with presets, offline operation and hallucination controls. VLM mappers such as Chandra and Nemotron keep getting format-level fixes, which suggests those backends are in routine use.
◆ Prediction
Expect more decode and parser limits, since the hardening touched many backends at once, and ASR presets to keep widening. The weekly-or-faster minor cadence shows no sign of slowing.
Promptfoo
5.0AI-ASSISTANTS
Promptfoo's feed has gone quiet except for small fixes to its code-scan action.
◆ Current state
The newest entries are code-scan GitHub Action patches: 0.2.1 updates type definitions and 0.2.2 mints the OIDC token after the CLI installs. The main evaluator's last visible release, 0.121.20 in July, added Claude Opus 5, Kimi K3 and websocket URL templating, following a run of releases that tracked each new frontier model.
◆ Where it's heading
The evaluator's rhythm is provider coverage plus red-team strategies, and the code-scan action is maintained on its own track. The feed shows no evaluator release since July, which may be a feed gap rather than a pause.
◆ Prediction
If the evaluator is still shipping, the next visible entry will likely add the latest frontier models; the feed doesn't show whether it stopped.
