Seed a forum you own, without dumping a week of posts in one night
Prove the domain, draft multi-user threads, approve every post, then let workers publish on a cadence. phpBB, XenForo, Discourse, and more.
Empty boards bounce people. A theme and a welcome sticky are not a community. Forum Seeder is the workflow we use on forums we actually run: helper users, multi-post threads, human approval, then a worker that posts through the real login (or Discourse API) on a human-like cadence.
It is not a tool for posting on other people's forums. If you cannot add a DNS record or an HTML file on the host, this product will refuse you. That is the point.
Product: Forum Seeder. Plans: Forum Seeder pricing.

Who it is for
Owners of phpBB, MyBB, SMF, XenForo, vBulletin, Discourse, Flarum, or NodeBB who already have a board (live or staging) and need starter conversations that look like back-and-forth, not a single admin talking to themselves.
Not for Reddit, Facebook, SEO agencies warming other people's communities, or anyone asking for an "undetectable bot".
The path
- Create an account and verify email.
- On the Forum Seeder page, Start free trial (3 days, Starter limits: 1 forum, 5 generated threads, 50 counted posts, 10 titles). Locked per email, signup IP, and later the forum domain.
- Claim the forum (name, base URL, engine). Discourse also needs an Admin API key at claim. See Discourse Admin API key.
- Prove ownership: DNS TXT or HTML file. See Prove you own the forum.
- Add forum users (the logins on your board). CSV import is
username,passwordwith no header. - Sync boards.
- Titles → Generate drafts or Thread Builder.
- Approve. Queue. Start workers.
Approval is the product
AI can draft. You still read. Quote repair runs so phpBB/XenForo markup does not ship broken. Thread Builder never calls a model: you write the posts, optionally with JPEG/PNG/GIF images.

Cadence, not a dump
Workers sleep between posts. Post now exists when a board is waiting on cadence, not as a firehose. Failed posts do not spend the counted-post meter. Original AI posts do not spend that meter either; extra replies and Thread Builder posts do. Generated-thread credits spend when an AI draft is created.
Exact meters: Forum Seeder pricing and wiki: billing.

- Will this post on forums I do not own?
- No. You must pass DNS TXT or HTML file verification. Workers pause if a later re-check fails.
- Do I have to accept every AI draft?
- No. Nothing goes live until you approve it. Thread Builder is fully manual if you do not want AI drafts.
- Is this the same as office-tool credits?
- No. Forum Seeder is a 3-day trial then Starter, Growth, or Pro monthly. Credits never pay for seeding.
