A side-by-side editorial comparison of HedgeDoc and Circle — release velocity, themes, recent moves, and the top alternatives to consider.
HedgeDoc vs Circle: at a glance
What is HedgeDoc?
HedgeDoc 1.x releases are now mostly advisories — security in, features rarely.
The 1.x line ships on a roughly six-to-eight-week rhythm, and almost every release leads with security fixes: HTML injection through an email localpart, YAML frontmatter denial-of-service, CSRF in the Gist export, a rate-limit bypass via the CF-Connecting-IP header, SVG upload script execution. Around that, the recent additions are operator controls — an external-link warning page with a whitelist, configurable login and signup rate limits, an option to restrict uploads to registered users or disable them entirely.
What is Circle?
Circle rebuilt itself around an AI that runs the community, not just answers in it
Circle ships a dated monthly release covering web, iOS, Android and its branded-app product, and the last six months have all pointed one direction. Circle Eclipse, announced in June and opened to every customer in late July, is a full re-skin of both member and admin surfaces plus a visual curriculum layout for courses. The AI layer that started as an answer bot now carries memory, roughly fifty domain-specific skills and project workspaces.
HedgeDoc vs Circle: editorial side-by-side
HedgeDoc
2.5COLLAB
HedgeDoc 1.x releases are now mostly advisories — security in, features rarely.
◆ Current state
The 1.x line ships on a roughly six-to-eight-week rhythm, and almost every release leads with security fixes: HTML injection through an email localpart, YAML frontmatter denial-of-service, CSRF in the Gist export, a rate-limit bypass via the CF-Connecting-IP header, SVG upload script execution. Around that, the recent additions are operator controls — an external-link warning page with a whitelist, configurable login and signup rate limits, an option to restrict uploads to registered users or disable them entirely.
◆ Where it's heading
This reads as a mature collaborative editor in hardening mode. New settings appear where an administrator needed a lever, not where a user asked for a feature, and the one substantial correctness fix in the window — data loss when five or more people edited a document at once — was a repair to the existing operational-transform client rather than new ground. Node 24 support and the removal of dead config options point the same direction: keeping a working product current.
◆ Prediction
Expect the next 1.x release to follow the same shape — one or more advisories plus a small configuration option — since every release in this window has done so.

Circle rebuilt itself around an AI that runs the community, not just answers in it
◆ Current state
Circle ships a dated monthly release covering web, iOS, Android and its branded-app product, and the last six months have all pointed one direction. Circle Eclipse, announced in June and opened to every customer in late July, is a full re-skin of both member and admin surfaces plus a visual curriculum layout for courses. The AI layer that started as an answer bot now carries memory, roughly fifty domain-specific skills and project workspaces.
◆ Where it's heading
The community platform is being reframed as a business-operations platform: Discover 2.0 supplies member demand, Circle AI does the work of structuring courses and spaces, and Circle Studios sells the operating labor outright. Circle MCP in April was the tell — community data became queryable and actionable from outside tools, which is only worth building if you expect the operator to be an agent. Event and CRM plumbing (public RSVPs, contact notes, custom profile fields on forms) has been quietly upgraded underneath to feed that loop.
◆ Prediction
Expect the fifty Circle AI skills to become the surface that gets extended next — either operator-authored skills or skills that act through Circle MCP rather than only inside the Circle UI.
