Pricing Compared
Starting price reflects the lowest paid tier, not the full cost for every team size or usage level.
Fast, keyboard-driven editor built specifically for engineering and product teams
Markdown compatibility makes content portable and developer-friendly
Bootstrapped, profitable company with a long track record of stability
Clean, focused feature set compared to broader all-in-one workspace tools
Cons
Fewer all-in-one features (databases, project management) than tools like Notion
Self-hosting requires technical setup and ongoing maintenance
Cloud pricing is per-plan-tier based on team size, which can jump significantly as headcount grows
Smaller integration ecosystem than larger enterprise wiki platforms
Advanced permission and audit features are reserved for higher-priced plans
HedgeDoc
Pros
Completely free and open source with no commercial tiers or paywalls
Genuinely lightweight and can run on minimal hardware like a Raspberry Pi
Real-time collaboration and revision history rival commercial collaborative editors
Built-in presentation mode turns notes into slides without a separate tool
Full data control for teams with self-hosting or compliance requirements
Cons
No officially operated hosted SaaS version, so self-hosting or finding a third-party host is required
No dedicated commercial support team or SLA, since it is a volunteer-maintained project
Interface and feature set are more minimal than fully featured commercial note-taking tools like Notion
Setup and maintenance require some server administration knowledge
History of multiple renamings (HackMD to CodiMD to HedgeDoc) can create confusion when searching for documentation or older resources
Use Cases
Outline
Engineering documentation — Engineering teams maintain runbooks, architecture docs, and onboarding guides in searchable, version-controlled collections.
Company-wide internal wiki — Organizations centralize policies, meeting notes, and cross-team knowledge in a single searchable workspace.
Self-hosted knowledge base for data-sensitive teams — Teams with strict data residency or compliance requirements self-host Outline on their own infrastructure instead of using a third-party cloud service.
HedgeDoc
Collaborative meeting and workshop notes — Teams and conference attendees use HedgeDoc as a shared hackpad to take collaborative notes in real time during meetings or workshops.
Self-hosted technical documentation — Developer teams self-host HedgeDoc to write and collaboratively edit markdown documentation without relying on a third-party SaaS tool.
Markdown-based slide presentations — A presenter writes talk notes in markdown and uses HedgeDoc's built-in presentation mode to deliver a live slideshow directly from the note.
