Scan any page with a real browser, see what it costs the planet per visit, and get a list of what to fix ordered by how much each change saves.
Trip Replay
Hi Product Hunt,
I built Carbonless because I could not tell how much of any website carbon number was measurement and how much was assumption.
So this one measures. A real browser loads your page twice: once cold, once with a warm cache, recording every request on the wire. Repeat-visit weight comes from the actual reload, not a constant. Findings name the specific files worth fixing and what each change saves. When a site serves the crawler a bot wall, the scan fails with that reason. No rating gets published for a page nobody actually sees.
For teams there is a JSON API and a GitHub Action that fails your PR when the preview deployment crosses a carbon or page-weight budget.
The measurement approach started as a peer-reviewed IEEE conference paper (https://ieeexplore.ieee.org/document/10223952). The prototype stayed an MVP for a while; this beta is a ground-up rewrite of it.
Everything is free while in beta. The methodology page lists every assumption, and Carbonless measured its own site: 0.028 g per visit, rated A+.
I'll be happy to hear your suggestions :)
