PostGate vs Post Bridge

A Post Bridge alternative built API-first, not add-on-first

Post Bridge is a real, well-regarded scheduling app for creators and agencies — a calendar UI, bulk video scheduling, and a growing platform list, with API access available as an optional add-on on top of a subscription. That's a good fit if a human is the primary user and automation is secondary. PostGate is built the other way around: the API is the product, not an add-on, with white-label environments and bring-your-own provider apps for teams and agencies embedding publishing into someone else's product. Below is a factual, sourced comparison so you can judge which fits your stack.

How PostGate and Post Bridge compare

Every Post Bridge figure below is sourced from post-bridge.com's own pricing and support pages as of this writing and may change — verify current details on their site before deciding. PostGate figures come from our own docs and pricing page, linked throughout.

DimensionPostGatePost Bridge
Starting price & free tierFree sandbox plan (10 posts/mo, no card required). Paid plans start at $4.00/mo. See /pricing.No permanently free plan; a 7-day free trial with no payment required upfront. Paid plans start at $29/mo (Creator, 15 connected accounts), up to $99/mo (Pro, unlimited accounts).
How the API is positionedThe API is the product — every plan is API access first, with a dashboard built on the same endpoints you call. See /docs.API access is documented as a paid add-on ($5/mo) on top of an existing Post Bridge subscription, enabled from the billing page rather than being the default product surface.
Platform app ownershipStore your own Meta, TikTok, LinkedIn, Pinterest, and other platform app credentials per organization on the white-label plan; quotas, approval status, and provider branding are isolated to your app. See /docs/environments.Publishes through its own platform integrations; public pages don't describe a bring-your-own-provider-app option for isolating a customer's own approval status and rate limits.
White-label branding & custom domainEvery embedded connection environment supports a branded logo, primary color, and a verified custom domain on every plan that enables white-label. See /docs/environments.Positioned as a creator- and agency-facing scheduling app with team member invitations on Growth and Pro; a branded, verified-custom-domain connection flow for a multi-tenant product is not advertised.
Webhook delivery modelSigned events (HMAC-SHA256 over timestamp and raw body) for post.published, post.partial, and post.failed, plus a test-delivery endpoint. See /docs/webhooks.Public support docs describe the API add-on and a CLI for posting, scheduling, and checking analytics; a signed webhook event system is not detailed on their public pages as of this writing.
MCP / AI-agent supportA hosted MCP server that creates a draft by default — a tool call must explicitly pass confirm: true to publish. See /docs/sdks-mcp.Advertises MCP agent integration on every plan, including a public agent-mode project on GitHub for connecting AI agents to posting across its supported platforms.
Why teams switch

Why teams switch to PostGate

White-label environments

Create a test or live environment with a brand configuration — product name, logo, and primary color — for the customer-facing connection experience. Read the environments guide.

Bring your own provider apps

Store your own Meta, TikTok, LinkedIn, and other platform app credentials per organization so your approval status and rate limits are yours alone. See the white-label plan.

Signed webhooks with delivery evidence

Subscribe to signed post.published, post.partial, and post.failed events, and inspect per-target delivery evidence instead of guessing why a post stalled. Read the webhooks guide.

SDKs in six languages, plus MCP

Build from generated clients in Node.js/TypeScript, Python, Go, Ruby, PHP, and .NET, or connect an AI agent to the hosted MCP server with draft-first publish safety. Read the SDKs & MCP guide.

Also worth knowing

Idempotent posts, so retries never duplicate

Idempotency keys

Pass a stable Idempotency-Key when creating a post and PostGate makes the logical request safe to retry for 72 hours — no accidental duplicate publishes from a retried request. Explore the docs.
