Tella vs BookStack
A side-by-side editorial comparison of Tella and BookStack — release velocity, themes, recent moves, and the top alternatives to consider.
Tella vs BookStack: at a glance
What is Tella?
Tella adds a Free plan, redesigns the editor, and broadens distribution into Intercom and beyond.
Tella is in a sustained editor-polish-plus-distribution cycle. The big change: a Free plan now sits alongside Pro, paired with an in-product AI support assistant. The editor was redesigned with a left-side toolbar, lighter UI, and a new transcript sidebar. New layouts (50/50 split) and finer camera-bubble positioning (3×3 grid plus three sizes across orientations) give creators more compositional control. Distribution widens with an Intercom Help Center integration and a refreshed tella.com.
What is BookStack?
BookStack's release stream is mostly security patches — five in three months, all responsibly disclosed.
BookStack is in a heavy security-patching phase on the 26.03 line, with five point releases since mid-March covering MFA brute-force, attachment permissions, webhook URL validation, registration role escalation, and hidden-page leakage. Every fix names the external researcher who reported it. Outside the security train, the v26.03 minor itself was the last meaningful feature release, shipping a theme-module reorganization and SMTP HELO change.

Tella
6.3COLLABMEETINGS
Tella adds a Free plan, redesigns the editor, and broadens distribution into Intercom and beyond.
◆ Current state
Tella is in a sustained editor-polish-plus-distribution cycle. The big change: a Free plan now sits alongside Pro, paired with an in-product AI support assistant. The editor was redesigned with a left-side toolbar, lighter UI, and a new transcript sidebar. New layouts (50/50 split) and finer camera-bubble positioning (3×3 grid plus three sizes across orientations) give creators more compositional control. Distribution widens with an Intercom Help Center integration and a refreshed tella.com.
◆ Where it's heading
The product is leaning into accessible-funnel-plus-creative-control: lower the barrier to start (Free plan), make the editor look modern and inviting, and embed videos where customers already are (Intercom). View notification controls and webhook events for viewer activity hint at an upcoming push toward integration-ready video analytics.
◆ Prediction
Expect more distribution surfaces (Slack, Notion-style embeds beyond Intercom) and AI features beyond the support assistant — likely auto-chapters, B-roll generation, or transcript-driven editing. The Free plan likely drives an experimentation phase before the next pricing/packaging tightening.
BookStack
5.0COLLAB
BookStack's release stream is mostly security patches — five in three months, all responsibly disclosed.
◆ Current state
BookStack is in a heavy security-patching phase on the 26.03 line, with five point releases since mid-March covering MFA brute-force, attachment permissions, webhook URL validation, registration role escalation, and hidden-page leakage. Every fix names the external researcher who reported it. Outside the security train, the v26.03 minor itself was the last meaningful feature release, shipping a theme-module reorganization and SMTP HELO change.
◆ Where it's heading
Expect the patch cadence to slow as the surfaced classes of vulnerabilities (auth, permissions, content filtering) stabilize, with the next minor likely concentrating on the theme-module API now that 26.03 has established the modules/ directory convention. The project's responsible-disclosure pipeline appears active and productive — multiple researchers, public credit, clear advisories — which is itself a competitive signal in the self-hosted wiki space.
◆ Prediction
A 26.03.6 within four weeks is likely given the current cadence, probably another dependency-bump rollup. The next minor (26.06 or 26.09 depending on the release calendar) will probably formalize the theme-modules surface and start adding API documentation for it.
