How Chirpie and Post Bridge differ

Post Bridge is built for creators publishing short-form video to many platforms: one flat $39 a month covers 15 accounts with unlimited posts, bulk video scheduling and an MCP server that signs in with OAuth. It does not publish threads on X or Threads, and it strips links from X captions because of what X charges for them. Chirpie covers fewer platforms today but publishes threads, keeps links in X posts, reports analytics on X, Bluesky, LinkedIn, Threads, Mastodon, Instagram and Facebook, and has a free plan.[1][3][5][6]

Choose Post Bridge if

  • You publish short-form video to TikTok, YouTube or Pinterest. All ten of Post Bridge's platforms post from one call, and Chirpie cannot post to those three today.[2]
  • You post at high volume. Posts are unlimited on both plans, so a creator posting hundreds of times a month pays the same $39.[1]
  • You manage dozens of accounts. Operator covers 99 accounts for $99 a month, then $1 per account with no ceiling, and adds team invites.[1]
  • You schedule video in bulk. Bulk video scheduling is on every plan.[1]
  • You want to add a connector from ChatGPT's app directory. Post Bridge's MCP server is listed there as a ChatGPT app, as well as in the Claude connector directory, and signs in with OAuth.[3]

Choose Chirpie if

  • You publish threads. Chirpie posts a thread as a native reply chain on X, Bluesky, Threads, Mastodon and Telegram in one call, and rolls it back if any part fails. How it works
  • Your X posts carry links. Chirpie publishes them as written, charging $0.25 per X link post on paid plans, or nothing extra on your own X keys. How it works
  • You need numbers from X, Bluesky, LinkedIn, Threads or Mastodon. Chirpie's analytics cover those, and Instagram and Facebook too; Post Bridge's cover TikTok, YouTube, Instagram and Facebook. How it works
  • You build in TypeScript. Chirpie publishes an SDK with typed errors, and every creating route accepts an Idempotency-Key. How it works

Chirpie and Post Bridge: common questions

Can I try Chirpie for free before choosing between it and Post Bridge?

Yes. The Free plan gives 50 posts a month, one connected account, the REST API and the MCP server, with no card. That is enough to wire up an agent and publish a real thread before paying anything.

Does Post Bridge charge extra for API access?

Not on its current plans. Its help centre says the API, the MCP server and the CLI are included on both Marketer and Operator, and that only some older plans still use a $5 a month API add-on. Chirpie includes the API and MCP on every plan, including Free.

Can Post Bridge post a thread on X?

No. Its help centre says it does not support scheduling threads on X or on Threads, citing technical and cost limits, and its llms.txt repeats that thread chains are not supported. Chirpie publishes threads of 2 to 25 posts on X, Bluesky, Threads, Mastodon and Telegram.

Why does Post Bridge remove links from X posts?

Its API reference says links are stripped from the caption before publishing to X because X charges far more for posts that contain a link, and suggests putting the link in a first comment or the bio. Chirpie keeps the link and passes X's cost on as $0.25 per X link post on paid plans.

Is Chirpie cheaper than Post Bridge?

For 1 to 3 accounts posting modestly, yes: Chirpie is free for 50 posts a month and $19 a month for 3 accounts, against $39. At 10 accounts, or at high volume, Post Bridge costs less, because $39 covers 15 accounts and its posts are unlimited.
