Stream your saves, not your screen.
One command turns a folder into a live, read-only link. Viewers follow every save in their browser, no account needed.

A screen share sends pixels. biga sends the files themselves, so viewers can select, search and scroll at their own pace.
Run it, share it, keep coding.
A whole session, start to rejoin, in under a minute. Reach in and it steps aside so you can drive.
Waiting for a link
Priya pastes your share link here. No sign-in, nothing to install.
Every save becomes a checkpoint.
biga hashes each file it reads. A burst of saves goes out as one checkpoint, and a save that changes nothing sends nothing.
- SHA-256per file
Bytes that match the last upload never leave your machine.
- 120 msof quiet
A burst of saves waits until the folder settles, then goes as one.
- 1 sat most
A long burst still flushes every second, so nobody waits on you.

Every checkpoint stays in the session for viewers to step back through.
Your .env stays on your machine.
This is the viewer your link opens, pulled apart. Every panel is built only from files that passed your ignore rules, and only the ones that changed travel.
Small tool, sharp edges filed off.
The parts you notice after a week of using it.
One command, every project.
List folders in a biga.json, or pass several on the command line. Each gets its own session and its own link.
Same link after a crash.
Run biga start again in the same folder. It rejoins the session and uploads only what changed.
Step back through every save.
Viewers scrub the checkpoint timeline and open the diff for any file.
Built for reading.
Quick open with ⌘P, syntax highlighting, and Follow, which opens each file as it's saved.

This is the actual viewer, playing back a finished session of this repository. The tree, the timeline and the diffs all work.
Already have a link?
Paste it here, or just open it. Viewers never need an account.
Share your next save.
Run a workshop, pair across timezones, or let people watch you build. Two commands, then send the link.
