Free on Windows - THE ADE and OS for Streaming
There's a modefor being live.
Mastery Lite is the free ADE with Streaming Mode built in. One toggle redacts secrets in your agents' output, swaps to your stream layout, and puts your real workspace back exactly as it was when you go offline.

Streaming Mode
Going live shouldn't mean rearranging your desk.
Most people stream their normal editor and hope nothing sensitive scrolls past. Lite has a mode for it. Flip it on when you go live, flip it off when you stop - nothing about your working setup has to change to accommodate the camera.
Secrets get masked on their way to the screen
Key-shaped strings - API keys, tokens, JWTs, whole .env dumps - are masked in terminal output, agent transcripts and the audit log. Nothing is changed underneath: turn Streaming Mode off and the full text is back.
It also stops you leaking it yourself
Copy something secret-shaped and it warns you. Revealing your .env is disabled. Your licence account and codes are hidden. Redaction can't be switched off separately either, so it can't be the thing you forgot.
You can always see that you're live
A red frame around the app and a pill in the top bar, because the dangerous state is the one you've stopped noticing.
A layout that only exists on stream
Streaming Mode keeps its own arrangement - panes, styles, viewport, even your drawings. Set it up once for the camera and it's there every time you go live.
Your real workspace comes back untouched
Switching off restores exactly where you were, in the workspace you left it in. The stream layout is a separate place, not a rearrangement of your work.
And it can drive OBS
Point it at OBS Studio and the app can talk to it, so going live doesn't mean alt-tabbing to start the scene.
For the vibe-coding channel
A terminal is a terrible thing to watch.
Scrolling logs make sense to you and nobody else. Lite gives the work a shape a viewer can follow: separate windows, each with a name, each visibly doing something. The build becomes the show instead of interrupting it.
01
Your viewers can see the work
Every agent gets its own window with its own title, prompt and output. Three running at once reads as a team on screen - not one process printing into a void.
02
Hours of stream, zero token bill
Lite runs local models - LM Studio, Ollama, any OpenAI-compatible endpoint - plus Cursor Agent. A four-hour build session costs the same as a four-hour idle: nothing.
03
One window to share, not eight
Agents, terminal, browser preview, code editor, notes and whiteboard live on one canvas. Capture a single window and your scene stops needing a director.
04
The VOD writes your recap
The Audit Log records what ran and when, so clipping the moment it worked - or explaining what broke - doesn't mean scrubbing an hour of footage.
05
It looks like something
Animated wallpapers, glass panes, a workspace that photographs well. Free tools usually look free. This one doesn't, and your thumbnail knows it.
06
Nothing to explain to your chat
No card, no trial countdown, no account wall in the way of the download. When someone asks what you're using, the answer is one link and they're building tonight.
The canvas
Three agents. One canvas.
Your agent, a live preview of what it is building, and a terminal - side by side, each one a window your audience can follow. Open another and the workspace re-tiles around it, so there is nothing to drag while the camera is on you.
No asterisks
Free, and here's exactly where it stops.
Lite is a real edition, not a demo - it has caps, and we'd rather you read them here than hit them mid-stream.
Windows 10 & 11
Get it and build something tonight.
One installer. Bring a local model or your Cursor login and you're working in a few minutes.

When you outgrow it
Lite is the workspace. HQ is the studio.
When three agents stop being enough - when you want a board they pull from, a council that argues, loops that keep going until the work is good, and the CLIs you already pay for - that's Mastery HQ.
