Tracespace View and Gerbv represent the two homes a Gerber viewer can live in: the browser tab and the desktop. Tracespace View (at tracespace.io/view) is a browser-based, open-source viewer that renders your Gerber files as SVG in the page — nothing to install, open the site and drop your files. Gerbv is a desktop application for Windows, macOS and Linux: free, open source (GPL-2.0-or-later), installed once, and used offline with your files never leaving the machine. This comparison walks through what that architectural difference means in practice — privacy, measurement, file handling and repeat use. It is a companion to our broader essay on online vs desktop Gerber viewers, and both tools also appear in the best free Gerber viewers roundup.
Getting started: install vs no install
Tracespace wins the first minute. On a borrowed machine, a locked-down work PC or a phone-adjacent moment of curiosity, a browser viewer is the only option that exists — there is nothing to download and no permission to ask for. Gerbv asks for one install, from the download page, and then repays it every time after: double-click, open the folder, done, with no network involved. Which cost matters more depends on frequency. Once a year, the browser wins. Every week, the installed tool wins.
Privacy: where do your files go?
A Gerber set is the complete manufacturing recipe for a board. With a desktop viewer the answer to “where do my files go” is boring in the best way: nowhere — Gerbv runs locally and works with no network connection at all. Browser viewers differ among themselves in how they handle uploads, and you should read each service’s own explanation before sending it a client’s design or an unreleased product. The desktop position needs no policy reading: the files stay on your disk, under your backup and confidentiality rules. For hobby boards that will be open-sourced next week this hardly matters; for contract work it can be the whole decision. Our Gerber viewer hub explains why we treat local viewing as the default for professional work.
Tooling depth: looking vs inspecting
Here the positioning diverges clearly. Tracespace is a viewer for rendering — it turns Gerber data into a clean SVG picture of your layers, and as its positioning states, it offers no measurement tools. Gerbv is built for inspection: stack several files, toggle and recolour layers, measure distances on the displayed image, and open report windows with statistics about the Gerber and drill codes in use, including aperture usage. It also exports the stacked view to PNG, PDF, PS, SVG and DXF for documentation and fab correspondence. If your question is “what does this board look like”, a renderer answers it. If your question is “is this board right — is the outline the size I designed, do the drills land on the pads, did anything land outside the profile” — you need measurement and reporting, and that is desktop territory. The routine is demonstrated in measuring distances in Gerbv.
File handling and repeat work
Gerbv views the full fabrication set together: Gerber RS-274X layers, Excellon drill files and CSV pick-and-place files, stacked for alignment checks — and it can open a whole directory of loadable files at once. It is a 2D viewer with honest limits: no 3D, no DRC, and no legacy RS-274D support. A browser session, by contrast, starts from zero each time: re-select the files, rebuild the stack, redo the setup. For a one-off look that is fine; for the tenth revision of the same board this week, the desktop tool’s persistence — same machine, same habits, same checklist — compounds.
Speed, once the novelty wears off
For a single file, the browser route can be genuinely quick — the site loads, the render appears, the question is answered. The balance shifts with set size and repetition. A fabrication package is a dozen files that must be selected together, stacked in the right order and revisited after every design tweak; on the desktop that becomes opening one folder in a tool that remembers nothing it should not and everything it should, while in the browser each revision restarts the ritual of gathering the same files into the same tab. Multiply by a week of iterations and the installed viewer’s head start in minute one becomes the browser’s deficit by Friday.
Verdict: choose by question
Choose Tracespace when you need a fast visual answer on a machine where you cannot or should not install anything, and the design is not sensitive. Choose Gerbv when the files are confidential, when the check involves measurements, drill alignment or reports, when you work offline or on restricted networks, or when Gerber checking is a recurring part of your week. The tools are not enemies: many engineers glance in the browser and verify on the desktop.
Frequently asked questions
Does Tracespace have measurement tools?
No — Tracespace View is a browser-based renderer that turns Gerber files into SVG images, and its positioning includes no measurement tools. If you need to measure an outline, hole or spacing, use a desktop viewer such as Gerbv, which measures on the displayed image.
Is it safe to upload Gerber files to a browser viewer?
That depends on the service’s handling and on the design’s sensitivity. A desktop viewer like Gerbv removes the question entirely: it runs offline and your files never leave your machine, which is why it is the safer default for client or unreleased work.
Can Gerbv open the same files as Tracespace?
Yes, and more of the set: Gerbv views Gerber RS-274X layers, Excellon drill files and CSV pick-and-place files together, so copper, drills and component positions can be checked in one aligned stack.
