Browser-based CAD: what you can actually do
Browser-based CAD has quietly caught up. Here's what you can draft, version, and share from a single tab, with no install, no license key, and no high-end laptop required.

For years, "CAD" meant a multi-gigabyte desktop install, a license key, and a machine strong enough to run it. That assumption is out of date. Browser-based CAD now handles real 2D drafting in a tab, and for a lot of work it removes more friction than it adds.
Here's an honest look at what you can and can't do with CAD in the browser, and why the browser is an advantage rather than a compromise.
What "browser-based CAD" actually means
It means the tool runs inside your web browser. There is nothing to download, no plugin, and no install step for you or your teammates. Open a tab on any modern computer and start drafting. Your drawings live with your account, not in a folder you have to back up, email, or remember the name of.
BranchCAD is exactly this: browser-based 2D CAD, free to start with no credit card.
What you can do in the browser today
Modern web CAD is not a toy sketchpad. In BranchCAD you can:
- Draft precisely. Draw lines and geometry with grid snapping and a live x/y coordinate readout, the way an engineering tool should feel.
- Work with the formats you already use. Import DXF and DWG drawings, and export your work as DXF, PDF, or SVG.
- Keep a real history. Branch a drawing to try a change, merge it back when
it's right, and restore any earlier version. No more
bracket_final_v3.dwg. - Collaborate live. Your whole team can edit the same drawing at the same time, with live cursors, selections, and comments.
All of that happens in the tab, with nothing installed.
What it is good for, and what it is not
Being honest saves everyone time. Browser-based CAD like BranchCAD is built for 2D work: engineering drawings, plans, schematics, and other technical line work. If you need full 3D solid modeling, that is a different category of tool. For 2D drafting and the team workflow around it, the browser is more than enough.
Why the browser is an advantage
Once you stop treating the browser as a limitation, the upsides stack up:
- Nothing to install or update. No version mismatches across a team, no IT ticket to get started.
- Any device. A laptop, a borrowed machine, a thin client. If it has a modern browser, it runs.
- A link, not an attachment. Share one URL and everyone is on the current drawing, not a copy that drifts.
- Versioned by default. Every edit is tracked, so going back is a click, not an archaeology project.
The point of browser-based CAD is not "CAD, but weaker." It is CAD without the install, the license dance, and the file chaos.
If you have been waiting for web CAD to be good enough for real 2D work, it is worth another look. Start designing free, no credit card, and draw your first line in the browser.
