HackMD, GitBook, and HedgeDoc are all solid tools. Here's where they fall short — and where GitBridge fills the gap.

Not "better features" — actual architectural gaps that force workarounds.
HackMD and HedgeDoc sync your Markdown text, but images stay on their servers. Open the repo without the app and images are broken. GitBridge commits everything — text, images, assets — to your repo on every save.
Architectural gap — 5+ yrs unfixedGitBook raised prices 2–3× in 2025. Mid-market teams on $10–20/user/month are actively looking for alternatives. GitBridge's flat $99/mo Pro plan covers unlimited collaborators — no per-seat math at renewal time.
Active migration waveHackMD requires Markdown fluency. HedgeDoc requires a server. GitBook works for technical writers but not for the PM who just needs to update a spec. GitBridge gives non-technical editors a Word-like interface while keeping Git as the source of truth.
Dual-audience problem solvedGitBridge uses flat-rate pricing. The competitors charge per seat — which compounds at scale and creates awkward renewal negotiations.
"Evaluate pricing carefully — some platforms charge per user (GitBook, Notion). For a 50-person team that's $500–1,000/month. GitBridge is $99. The math is obvious."
