Post Bridge alternative (API-only)

Post Bridge is a social media scheduler and cross-poster: write a post once and publish it to several networks from one dashboard. Its site says it's "built for one person marketing a business", as opposed to team tools like Buffer and Hootsuite. It supports multiple accounts per platform, carousels, bulk video scheduling, analytics (in beta) and founder support.

For developers it has a REST API with an API key from the dashboard, and an MCP server at one URL that most clients join over OAuth. Its MCP page lists 16 tools covering scheduling, analytics, accounts, post results and media.

Read on post-bridge.com/pricing on 2026-11-01. Both plans have a 7-day free trial, and refunds can be requested within 7 days of a charge. There's a yearly toggle advertising "2 months free", but the page doesn't list the yearly prices.

• Marketer: $39/mo. 15 connected accounts, unlimited posts, API included, MCP agent connect, multiple accounts per platform, scheduling, carousels, bulk video, analytics (beta).
• Operator: $99/mo. 99 accounts included, $1 each after, no account limit, everything in Marketer plus team invites.
• Free: not shown as a plan. The FAQ says free users get 5 posts; account limits for free users aren't listed.

The agents page says API access is "included on every plan" and the key is "only for the REST API and URL-only clients"; MCP uses OAuth instead. It shows POST /v1/social-accounts/connect-link, which returns a link the account owner opens to approve the connection, and describes creating a post with a scheduled_at timestamp and reading per-account results back. We couldn't read a full REST reference: the API reference page rendered no content when fetched, so endpoint paths beyond these aren't listed here.

Post Bridge posts to ten networks today, including TikTok, Instagram, YouTube, Threads, Pinterest, Facebook and Google Business. We have X, Bluesky, LinkedIn, Mastodon and Telegram live, with the others coming. If you need any of those networks now, use Post Bridge.

It also has the app. If you sometimes want to drag a post on a calendar or bulk-schedule a folder of videos, that's a real feature we don't have and don't plan to build.

Price at small and mid counts. Post Bridge starts at $39 for up to 15 accounts. We're $0 for 3 active accounts on Free, $9 for 5, $19 for 10 and $29 for 15. Between 16 and 98 accounts Post Bridge jumps to $99, while we're $29 at 25 and $54 at 50. At 100 accounts the two are close: $100 against our $79. See pricing.

Idle accounts. Post Bridge counts connected accounts. We count accounts that published that month. For client work or an app whose users post now and then, that gap grows with the account count.

API behavior. We run preflight checks before sending (length, media count, duplicates, daily caps, account status) and return each problem with a fix, retry retryable failures on a fixed schedule, and accept idempotency keys so a retried request doesn't double-post. How Post Bridge handles these isn't documented on the pages we read, so we don't compare them. Our full contract is in the docs, and the MCP server uses the same calls.

A short way to pick, using only the prices and features above. If you want a scheduler with AI generation or self-hosting instead, see Postiz.

• You open the app most days to schedule or bulk-upload video: Post Bridge.
• You need TikTok, Instagram, YouTube, Threads or Pinterest this month: Post Bridge.
• You call the API from code or an agent and never open a dashboard: us, starting on Free.
• You have 16 to 98 accounts: Post Bridge is $99; we're $29 to $79 depending on how many posted.
• You have about 100 accounts that all post every month: the price is close, so pick on network coverage and API behavior.

Social accounts map to our accounts. POST /v1/social-accounts/connect-link maps to POST /v1/connect-links, which takes an external_ref (your client or user id) and a redirect_url; links expire after 7 days by default. A post to several social accounts is one POST /v1/posts with several ids in accounts, and scheduled_at keeps its name and takes ISO-8601. Media goes in as public URLs in media. Accounts need reconnecting, since OAuth grants don't move between apps.
