Docling vs Roo Code
A side-by-side editorial comparison of Docling and Roo Code — release velocity, themes, recent moves, and the top alternatives to consider.
Docling vs Roo Code: 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 Roo Code?
Roo Code's visible releases are CLI point versions aimed at driving the agent from a script.
The four available entries are all Roo Code CLI releases from early March 2026, versions 0.1.14 through 0.1.17, shipped over roughly 36 hours. Every one of them touches programmatic control: a flag to supply a custom UUID session ID when creating tasks, a flag to choose which shell runs inline commands, and two fixes to stdin-stream mode covering follow-up message routing after a clarification question and truncated command output before the done event.

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.
Roo Code
0.0AI-ASSISTANTS
Roo Code's visible releases are CLI point versions aimed at driving the agent from a script.
◆ Current state
The four available entries are all Roo Code CLI releases from early March 2026, versions 0.1.14 through 0.1.17, shipped over roughly 36 hours. Every one of them touches programmatic control: a flag to supply a custom UUID session ID when creating tasks, a flag to choose which shell runs inline commands, and two fixes to stdin-stream mode covering follow-up message routing after a clarification question and truncated command output before the done event.
◆ Where it's heading
This is the surface of the product being hardened for automation rather than for interactive use. Session IDs that a caller can set and validate, deterministic stdin streaming, and a selectable shell are the pieces you need to embed an agent in someone else's pipeline. The releases are small, fast and narrow, and the extension itself is not represented in this feed — so this reads as one component's release channel, not the product's.
◆ Prediction
The run of stdin-stream fixes suggests further work on that path, but the newest entry here is from March 2026 and nothing has followed, so the current state of the CLI is not visible from this feed.
