firsto.co
In short: Firsto (firsto.co) accepts product launch/listing. It is free to submit, takes a moderate amount of preparation, and scores 84/100 on our impact ranking (high impact).
Launch your tool with a unique tagline, screenshots and founder profile linking to your tool.
Use original launch copy; no vote manipulation; review or queue may apply. Link treatment varies by tier/page.
Priority is high, which sets the band. It is free and moderate to complete, which adjusts it within that band. The score ranks your queue — it is not a measure of domain authority.
