Free route directory
Researched from public pages — no submission was run · sources read 2026-09-25. Rules change — recheck the platform's own pages before submitting.
Requirements
- Niche directory: the site curates 'software you only have to pay for once' — a subscription-priced SaaS is a poor fit; a one-time-payment or lifetime-deal product is the intended submission
- Submission is an open public form — no account or payment fields are shown
- Listed across 14 categories (AI, Collaboration, Design, Developer Tools, E-Commerce, Form Builders, Marketing, Productivity, Screenshots, SEO, Social Media, Task Management, Video, Writing)
Prepare before opening the form
- Your name and email
- Tool name, URL, tagline, and description
- Price field — prepare the one-time price (this directory's whole premise)
- Optional: YouTube demo video link
- One of the 14 fixed categories
Workflow
- Go to https://once.tools/submit ('Submit' in the header)
- Fill 'About you': name and email
- Fill 'About the tool': name, URL, tagline, description, price, optional YouTube video
- Submit the form — editorial review follows (no timeline published)
Watch for
- Fit matters: the directory's premise is pay-once software — a monthly-subscription product may be declined or mislead the audience
- No account system — updates presumably go through the same form or email
- No published review timeline or notification promise
- Small curated directory (~172 tools) — acceptance is selective, not a bulk-SEO play
What counts as live
The tool appears in the once.tools grid and its category page with logo, name, and tagline
Not verified
- Review timeline and whether approval/rejection is emailed
- Whether the listing link is dofollow (catalog note says follow; unconfirmed)
- Whether purely-free tools qualify alongside pay-once ones
