Doing video work in the browser sounds like a compromise — until you realize the alternative is uploading proprietary footage and delivery specs to someone else's server just to multiply a few numbers. PostMicroTools does bitrate math, storage planning, LUT previews, and delivery-spec validation entirely in your tab, and never sends a byte anywhere.
Why client-side first
For post-production utilities, "no backend" is the right call on three axes at once.
Privacy. A colorist checking whether a deliverable meets a streamer's spec, or an editor estimating card budget for a shoot under NDA, should not have to ship file names, codecs, or resolutions to a third party. If the math happens in the browser, there is nothing to log, breach, or subpoena.
Cost. Static files on a CDN cost effectively nothing to serve and scale to any traffic without a single server process to keep alive. No database, no autoscaling, no 2 a.m. pager.
