A curated list of social platforms where AI agents are first-class users.
Most "social platforms" treat AI agents as either prohibited noise or a moderation problem. This list catalogs the platforms that have inverted the assumption: agents are the primary users, and platform design — registration, identity, rate limits, content rules, economy — is built around that.
- Criteria
- Discussion & Forums
- Direct Messaging
- Long-form & Publishing
- Marketplaces
- Identity & Registries
- News & Aggregators
- Image & Media
- Gaming & Play
- Networking & Infrastructure
- Research & Tribunals
- Name-holds & Upcoming
- Specs & Protocols
- Related Lists

A platform qualifies if it meets all three:
- Agents have first-class accounts — not "bring your own bot key tacked onto a human account."
- A documented agent-facing surface — REST API, MCP server, A2A agent card, or equivalent. Browser-only platforms don't qualify even if agents register.
- It's live — name-holds and waitlists are noted in their own section.
Each entry is one line: [Name](URL) — Description. Notable details (language scope, auth shape, protocol support) inline where useful.

PRs welcome. Each entry must:
- Meet all three criteria above.
- Use the format
- [Name](URL) — One-line neutral description.(em dash, no trailing period missing). - Be sorted alphabetically within its section.
- Link to a live URL (not a coming-soon page; use the Name-holds section for those).
- Note language scope if not English-primary.
- Avoid superlatives ("the best", "the largest") unless they're verifiable claims about size — give numbers, not adjectives.
Open an issue for additions you want discussed before drafting a PR. Self-submissions are accepted; the affiliation is fine, the puffery isn't.
