PostGate vs Buffer

A Buffer alternative for teams building their own product

Buffer is a real, mature, well-known product — a UI-first social media scheduler that's been around for over a decade, with a straightforward per-channel pricing model and a genuinely useful free tier. That's a good fit for a team that wants a dashboard to log into and post from. PostGate is built for a different job: teams building their own product — an agency tool, a client dashboard, an AI agent — on top of a posting API, with multi-tenant environments, signed delivery evidence, and white-label branding as first-class primitives instead of a UI you use directly. Below is a factual, sourced comparison so you can judge which fits your stack.

How PostGate and Buffer compare

Every Buffer figure below is sourced from buffer.com/pricing and developers.buffer.com as of this writing and may change — verify current details before deciding. PostGate figures come from our own docs and pricing page, linked throughout. For a deep dive specifically on Buffer's API migration (its legacy REST API retiring February 1, 2027, and the new GraphQL API's public beta status), see /compare/buffer-api-alternative.

DimensionPostGateBuffer
Deployment modelA managed, multi-tenant API. No infrastructure to run — you call an HTTPS endpoint and PostGate operates the queues, workers, and delivery pipeline for your own product.A hosted, UI-first scheduler you and your team log into and use directly. An API exists alongside it (see our API-specific comparison), but the product itself is the dashboard, not a developer platform.
Starting price & free tierFree sandbox plan, no card required. Paid plans start at $4.00/mo. See /pricing.Free plan for up to 3 channels (10 scheduled posts per channel). Paid plans are priced per channel: Essentials at $5/channel/mo and Team at $10/channel/mo (both roughly 20% cheaper billed yearly), with volume discounts on higher channel counts. There is no flat per-workspace starting price — cost scales directly with the number of channels connected.
Who owns platform app approvalOn the white-label plan, bring your own Meta, TikTok, LinkedIn, and other provider app credentials per organization — your approval status and rate limits are yours alone. See /docs/environments.Users connect channels through Buffer's own registered platform apps — there is no documented option to swap in your own Meta/TikTok/LinkedIn app credentials so approval status and rate limits are separated per customer.
White-label & multi-tenant supportEvery embedded connection environment supports a branded logo, primary color, and a verified custom domain on every plan that enables white-label. See /docs/environments.Buffer retired its dedicated Agency plan in November 2025; agency-scale use is now handled through per-channel volume discounts on the Team plan, plus a "branded reports" feature for client-facing analytics exports. Buffer's public materials don't document a white-labeled, verified custom domain for an end-customer connection flow — Buffer itself remains the branded product your clients would log into.
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.Buffer's public developer docs at developers.buffer.com don't list a webhooks guide among their documented topics as of this writing — detecting state changes appears to rely on polling the API rather than a native push/event mechanism.
SDK & developer toolingGenerated clients for six languages/runtimes — Node.js/TypeScript, Python, Go, Ruby, PHP, and .NET — from one OpenAPI contract. See /docs/sdks-mcp.Buffer's new GraphQL API ships an MCP server and a CLI, and its docs highlight working with AI tools like Claude, ChatGPT, and Cursor. Access is metered per plan (Free: 1 API key / 1 app client / 3,000 requests per 30 days; Essentials: 3 / 3 / 7,500; Team: 5 / 5 / 15,000); we found no published SDKs across multiple traditional languages.
Idempotent retriesA stable Idempotency-Key makes a logical create-post request safe to retry for 72 hours — no accidental duplicate publishes. See /docs/idempotency.Not documented as a public API contract in Buffer's developer guides — we found no published idempotency-key mechanism for retried create-post requests.

Buffer is a real product — for the right team

A dashboard you use is a different product than an API you build on

Buffer being a mature, well-known, UI-first scheduler is a genuine, notable strength — a straightforward per-channel price, a real free tier, and a decade-plus of product polish for a team that just wants to log in and schedule posts. That's the right tool for a marketer or a small team managing their own channels directly. PostGate takes the other side of that tradeoff deliberately: there is no PostGate dashboard for end customers to log into — it's a managed, multi-tenant API where environments, custom domains, and provider-app isolation are configuration your product exposes to its own users, not a UI we ship. If you want a finished scheduler, Buffer is a legitimate option; if you're building an agency tool, a client dashboard, or an AI agent that needs to post on behalf of many customers under your own brand, that's what PostGate is built for. See /whitelabel.

Why teams switch

Why teams switch to PostGate

No infrastructure to operate

No dashboard to white-label around, no per-channel pricing to pass through to your own customers — call an HTTPS endpoint and PostGate operates the queue, retries, and delivery pipeline. Explore the docs.

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.

Signed webhooks with delivery evidence

Subscribe to signed post.published, post.partial, and post.failed events, and inspect per-target delivery evidence instead of polling for state changes. 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 at postgate.studio/mcp with draft-first publish safety. Read the SDKs & MCP guide.

Honest gaps

Where PostGate isn't the better fit yet

No native bulk/batch endpoint

Buffer's dashboard supports bulk scheduling as a UI feature; PostGate has no dedicated bulk/batch create-post endpoint today — you loop over the single-post API.

No native n8n/Zapier/Make integration

There's no packaged PostGate node for the popular automation platforms — you wire it up yourself against the API. See our n8n workflow guide.

No built-in approval-workflow feature

Buffer's Team plan includes a native approval-workflow UI; PostGate has no equivalent built-in feature — you'd implement an approval step yourself on top of the API. See our approval-step 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.
