Conditional 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.

What the free route requires

Free plan requires signing in with a Google or GitHub account
Free submissions join a queue with a stated '180+ days wait at current pace'
Free listings 'may be rejected due to limited free slots'
Free plan grants a permanent link only 'with backlink maintenance' — a reciprocal backlink appears to be required to keep it

Online tool/website to list; directory is general-purpose (AI, Business, Productivity, Development, Design, etc.)
Google or GitHub account for authentication
Free tier promises '3 dofollow links' — categories/tags chosen at submission affect link count

Open https://600.tools/submit
Authenticate via Login with Google or Login with GitHub
Choose plan: free (queue) / $9.9 listing (instant) / $19.9 featured (instant + 7 days on top)
Complete the submission form inside the signed-in area
Free route: wait in queue (180+ days stated); paid route: published immediately

The submit page is a login wall — the actual form is not publicly visible, so field list is unknown
Free tier explicitly warns of 180+ day wait and possible rejection — budget time or expect to pay $9.9
'Backlink maintenance' wording on the free plan implies you must keep a link back to 600.tools; failure may remove the listing
Strike-through prices ($14.9→$9.9, $39.9→$19.9) are perpetual-sale framing, not real deadlines
Same operator/template as featuredtool.com and dirs.cc (shared @blankwebdev X handle) — identical pricing structure

Product has a public item page at 600.tools/item/<slug> appearing in category/tag listings
