The fitter is free and always will be. Paid tiers turn it into a system of record — added only as your lab needs them.
The full browser tool, no account.
For working scientists who fit curves every week.
For ISO 17025 & 21 CFR Part 11 environments.
Pro and Compliance are in active development. Prices shown are indicative early-access figures and may change before launch — the free fitter is fully available today.
Prism is powerful but costs hundreds per seat per year, needs installing, and ties analysis to a desktop. DoseFit's wedge is the opposite: instant, in-browser, shareable, and honest about uncertainty — with a literature comparison Prism doesn't offer. The paid tiers then add the compliance and record-keeping that neither a fitter nor a spreadsheet gives you.
