Proto.io plans & pricing
| Plan | Monthly | Annual | Billing | Notes | Source |
|---|---|---|---|---|---|
| Free STALE · 2026-09-10 | $0 | — | Flat monthly | $0 per month. 1 user, 1 active project, 5 prototype screens and 10 MB of storage. The 5-screen ceiling makes it a demo rather than a working tier. | proto.io |
| Freelancer | $29 | — | Flat monthly | $29/month month-to-month; $40... corrected: $24/month paid annually. Includes 1 user and 5 active projects with unlimited reviewers. Priced as a flat plan with a bundled user count, not per seat, so a second editor means moving up a tier rather than buying a seat. | proto.io |
| Startup | $49 | — | Flat monthly | $49/month month-to-month; $40/month paid annually. 2 users, 10 active projects, unlimited reviewers. 'Active' projects are the metered unit — archiving a project frees a slot. | proto.io |
| Agency | $99 | — | Flat monthly | $99/month month-to-month; $80/month paid annually. 5 users, 15 active projects, unlimited reviewers. Works out cheaper per editor than Startup, which is the usual reason agencies jump straight here. | proto.io |
| Corporate | $199 | — | Flat monthly | $199/month month-to-month; $160/month paid annually. 10 users, 30 active projects, unlimited reviewers. The top published self-serve tier — beyond 10 users no higher price is published. | proto.io |
Last verified 2026-11-01. STALE marks a plan we have not re-checked at its source in over 30 days. 1 of 5 plans above is marked. Re-verified 2026-09-10 and unchanged — this was the cleanest vendor in an earlier version of this record. proto.io/en/pricing publishes the month-to-month price and the annual-billed monthly rate together for every tier, and all five matched exactly: Free $0 (1 user, 1 active project, 5 screens, 10 MB), Freelancer $29 monthly / $24 annual, Startup $49 / $40, Agency $99 / $80, Corporate $199 / $160, with user counts 1 / 2 / 5 / 10 and active-project caps 5 / 10 / 15 / 30. The '15 day trial, no credit card required' was re-confirmed. The page advertises 'up to 20%' for annual, a ceiling rather than a per-plan saving, so the annual discount stays not recorded everywhere.

This standing as a plaque
Proto.io currently holds a bronze deskmark here — Rank 14 of 14 · Design Tools. Anyone may show it. There is nothing to apply for, nothing to pay, and displaying it changes no score: the standing comes from the published algorithm, which never reads commission data. We never ask anyone to show it, and its link carries rel="nofollow".
The image is drawn from our live data, so it follows the standing rather than freezing it: if Proto.io moves up or down a tier, the plaque on your own site says so at our next publish. Nothing is tracked beyond the ordinary web-server log that records any image request.
