Live class starts in 5 minutes and one student can’t install Zoom.
Students join with a link. No software, no platform account. Multiple presenters in the same canvas: guest lecturer + main instructor + screen-share. Push to YouTube for the public lecture series, your LMS recording for the gradebook, and Vimeo / Mux / Bunny / Cloudflare Stream archive at the same time.
Built for the education workflow
Browser-only for students and TAs
No software install, no platform account. Anyone with a link joins the class in 30 seconds.
Screen-share + demo capture
Slides, code editors, design tools, all as browser sources directly in the canvas. No NDI bridge.
Per-session scaling
Small class? Starter plan. Big public webinar? Bump to Business for the session. Modular per-input + per-output pricing means you only pay for what you used.
Recording archive ingest
Push the same broadcast to your LMS recording archive (Vimeo, Mux, Bunny, Cloudflare Stream) while it goes live on YouTube.
Why instructors pick TRaX
Live classes break when the tooling adds friction. A student who can't install Zoom is a student who didn't show up. A browser link is the lowest-friction joining experience that still produces a broadcast-grade recording.
- Students join with a link. Your LMS keeps the gradebook, TRaX handles the live
- Multiple presenters in the same canvas, with guest lecturer + main instructor at once
- Delivery runs on US edge nodes we operate, so quality is consistent instead of best-effort
What a live class or cohort session runs at
Teaching online is a legibility problem before it is a video problem. These settings are chosen so that code, equations and slides survive the trip to a student on a laptop.
- Program canvas
- 1080p30
- Small type is what breaks first. A 1080p canvas at 6 Mbps holds a shared editor or a spreadsheet legibly, where 720p turns a monospace font into a suggestion.
- Student access
- A link, no account, no download
- A cohort that must create accounts loses people at the account step, and a locked-down school laptop cannot install software even when the student is willing.
- Co-teaching
- Several presenters on one canvas
- A lead instructor and a teaching assistant can both be on the scene, so questions get handled by the assistant without the lead losing the thread of the lesson.
- Screen-share
- Placed beside the presenter, not over them
- Students retain more from a person next to a slide than from a slide alone, and keeping the instructor visible is a composition choice you make rather than a mode you toggle.
- Archive
- Recorded, stored per GB, handed to the LMS
- An hour of 1080p30 comes to roughly 2.7 GB, so a fourteen-week course archived in full is a storage figure you can put in a budget at the start of term.
Programs run at 1080p as standard, and up to 1440p when every destination you have enabled can accept it — the canvas is clamped to the least capable one in the set.

Things that matter more in education than elsewhere
Three constraints that are minor annoyances for a creator and genuine planning items for an institution.
The session runs at whatever format it opened with
Canvas resolution and frame rate are read at go-live and hold until the stream ends. A lecture that starts lower because an instructor was nervous about their home connection stays there, and so does the recording that lands in the LMS. Put the format in the course template and take the decision away from the person pressing start.
Captions are a workflow you still have to build
Streaming and recording give you an artefact; they do not produce a transcript or caption track. If your institution carries an accessibility obligation, decide now who captions the archive and how fast, because the recording is what makes that possible rather than what makes it done.
A recorded class contains identifiable students
The moment a session with participating students is recorded and retained, it is student data under whatever regime governs you. Decide before term whether students appear on camera, how long recordings live and who can be handed a copy — that is a policy question, and no platform setting answers it for you.
