Docling vs opencode
A side-by-side editorial comparison of Docling and opencode — release velocity, themes, recent moves, and the top alternatives to consider.
Docling vs opencode: at a glance
What is Docling?
Docling keeps swallowing new formats, and now the parsing engines behind them are swappable.
Docling releases every three to four days, alternating feature drops with tight fix releases. The current one is purely corrective: DOCX headings detected by outline level when the style is not literally named Heading, Markdown tables keeping their last cell without a trailing pipe, and the service client serializing engine options in full. Format coverage now spans PDF, Office, ODF, HTML, JATS, email, audio and video.
What is opencode?
Provider compatibility is where opencode spends its releases now, not features.
opencode ships a patch release every day or two, and the work splits cleanly in two: core changes that keep an expanding roster of model providers behaving correctly, and desktop polish covering localisation, right-to-left layout and session handling. The recent releases fix Kimi system prompt selection for Moonshot, reasoning-effort handling for xAI, sampling defaults for DeepSeek V4 Flash, and Meta prompt routing for Muse models. Session compaction was reworked to keep recent turns whole and produce summaries that smaller models can actually use.

Docling
6.3AI-ASSISTANTS
Docling keeps swallowing new formats, and now the parsing engines behind them are swappable.
◆ Current state
Docling releases every three to four days, alternating feature drops with tight fix releases. The current one is purely corrective: DOCX headings detected by outline level when the style is not literally named Heading, Markdown tables keeping their last cell without a trailing pipe, and the service client serializing engine options in full. Format coverage now spans PDF, Office, ODF, HTML, JATS, email, audio and video.
◆ Where it's heading
The engine layer is where the interesting movement is. Docling is shifting from one opinionated pipeline to a set of interchangeable layout, table and OCR backends the caller picks per run, which turns the library into a harness for models rather than a fixed parser. A second thread: the project shipped agent skills for itself in v2.118.0 and a separate docling-client package in v2.120.0, both pointing at being consumed programmatically rather than only imported. The structural-inference work — heading levels from font weight, now from DOCX outline levels — shows the parser learning to read documents that never declared their own structure.
◆ Prediction
Expect the engine-selection surface to keep widening, with OCR joining layout and table structure as a CLI-selectable backend. The steady stream of format-specific crash fixes suggests coverage is outrunning hardening, so more of these short corrective releases are likely between feature drops.
opencode
5.0AI-ASSISTANTS
Provider compatibility is where opencode spends its releases now, not features.
◆ Current state
opencode ships a patch release every day or two, and the work splits cleanly in two: core changes that keep an expanding roster of model providers behaving correctly, and desktop polish covering localisation, right-to-left layout and session handling. The recent releases fix Kimi system prompt selection for Moonshot, reasoning-effort handling for xAI, sampling defaults for DeepSeek V4 Flash, and Meta prompt routing for Muse models. Session compaction was reworked to keep recent turns whole and produce summaries that smaller models can actually use.
◆ Where it's heading
The centre of gravity has moved from building the agent to making it survive contact with a dozen incompatible provider APIs. Each release absorbs another provider's quirks — reasoning field names, PDF vision support, device-code login, retry semantics — which is the cost of positioning as provider-neutral. The parallel investment in locale coverage and right-to-left support points at a deliberate push beyond English-speaking users, with community contributors carrying much of it.
◆ Prediction
Expect the patch cadence to hold, with more provider-specific compatibility fixes as new models land and further desktop localisation. A minor-version bump would likely be needed for anything beyond this maintenance pattern, and nothing in these entries signals one.
