What is HedgeDoc?
A collaborative markdown editor on a security-driven maintenance cadence.
HedgeDoc's 1.x line ships every one to two months and is dominated by security response. Recent releases carry seven advisories between them — HTML injection via an email localpart, YAML frontmatter denial of service, CSRF in the Gist export, a rate-limit bypass through CF-Connecting-IP, a permission-value validation gap, missing upload security headers, and script execution in uploaded SVGs. Around those sit configuration knobs for the external-link warning, webp uploads, and rate limits.
What is Outline?
Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.
Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.

HedgeDoc
2.5COLLAB
A collaborative markdown editor on a security-driven maintenance cadence.
◆ Current state
HedgeDoc's 1.x line ships every one to two months and is dominated by security response. Recent releases carry seven advisories between them — HTML injection via an email localpart, YAML frontmatter denial of service, CSRF in the Gist export, a rate-limit bypass through CF-Connecting-IP, a permission-value validation gap, missing upload security headers, and script execution in uploaded SVGs. Around those sit configuration knobs for the external-link warning, webp uploads, and rate limits.
◆ Where it's heading
Two threads run in parallel. The perimeter work reduces attack surface and maintenance burden at once: old API endpoints and unused config are deleted, Node 18 support is dropped now that its security window has closed, and features added in one release tend to gain an off switch in the next. The second thread is realtime correctness — concurrent-editing data loss, connections dropped mid-handshake, operations discarded during revision gap recovery — which is the only work aimed at the core editing experience rather than its edges.
◆ Prediction
Expect the 1.x line to continue as security and correctness maintenance, with more legacy endpoints and configuration removed rather than new editing features added.
Outline
6.3COLLAB
Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.
◆ Current state
Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.
◆ Where it's heading
Outline is positioning itself as an agent-native knowledge base rather than just a polished wiki. The pattern across the last several releases is deliberate: MCP support expanded significantly in April, Open Knowledge Format export added portability in September, and WebMCP makes the agent integration surface browser-accessible. The OKF export is also a meaningful portability move — structured markdown bundles that survive outside Outline reduce lock-in risk and could attract teams evaluating it against more closed alternatives.
◆ Prediction
Outline will likely expand the WebMCP tool surface — the April MCP work gave them a solid set of structured tools to expose, and WebMCP makes those available without setup friction. Expect more agent-facing capabilities (summarization, cross-document linking, task extraction) rather than another round of baseline UX polish.
