The median wait across this directory is seven days, and the tail is long: fifteen platforms take three months or more, with Sidehunt's free calendar running four months out and Awesome Indie holding three thousand products in the queue ahead of you. None of that is any use during a launch week that has already started. These twelve publish within two days, and several of them within two minutes.
Speed is usually bought, so read what each one takes for it. Show HN, Indie Hackers and Product Hunt are fast because posting is the product and the audience decides what happens next. MicroLaunch and Startups.fm are fast because you paid. Neeed, AI Toolz Dir, Wayfind.io and ToolDisk are fast because there is no editorial gate at all, only a badge check, which is also the reason an instant listing on a small directory is worth less than a week on a board that reads submissions. Use these to fill a launch week, not to build one.
Across the 12 platforms on this list, median approval time is 1 day, 10 of 12 give dofollow backlinks, 10 are free to submit. Median domain rating: 57.
