Platforms ​

Socifyr publishes to 18 platforms. OAuth platforms connect with one click; credential-entry platforms (Telegram, Discord, Mastodon, Nostr, Slack, Dev.to, Hashnode, Tumblr) use a bot token, webhook, access token, keypair, or API key you create yourself — no app review, ~2 minutes to set up.

Universal guarantees ​

  • Per-channel retry — a failure on one platform never loses the others.
  • Idempotency keys — a retried publish never duplicates a post.
  • Plain-language failure reasons with fix hints, on every surface.
  • Machine-readable limits — PLATFORM_CONSTRAINTS in @socifyr/shared.
