PostGate vs Zernio
A Zernio alternative for teams that want to own the brand
Zernio is a real, developer-first REST API and hosted MCP server covering 16 social platforms, with genuinely free access for your first two connected accounts and a broader published SDK language list than most competitors in this space. It's a strong technical option if you'd rather pay per connected account than per plan tier. PostGate takes a different shape: white-label branded environments with a verified custom domain, bring-your-own provider apps isolated per organization, and flat-tier pricing instead of a per-account meter. Below is a factual, sourced comparison so you can judge which fits your stack.
Side by side
How PostGate and Zernio compare
Every Zernio figure below is sourced from zernio.com and docs.zernio.com 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.
| Dimension | PostGate | Zernio |
|---|---|---|
| Starting price & free tier | Free sandbox plan, no card required. Paid plans start at $4.00/mo. See /pricing. | First 2 connected accounts free indefinitely (unlimited posts, full API access, no card required). Beyond that: $6/mo per account for accounts 3–10, $3/mo per account for accounts 11–100, and $1/mo per account for 101+, with no base or setup fee. |
| Pricing model | A flat price per plan tier; unlimited posting on every paid plan, and you scale by connected profiles within a tier rather than a continuous per-account meter. See /pricing. | Purely usage-based on connected accounts — no post cap at any tier, but cost scales linearly per account rather than in plan steps, so the bill grows continuously as you connect more profiles. |
| SDK language coverage | Generated clients for six languages/runtimes — Node.js/TypeScript, Python, Go, Ruby, PHP, and .NET — from one OpenAPI contract. See /docs/sdks-mcp. | Documents SDKs for Go, Ruby, Java, PHP, .NET, and Rust, plus Node.js and Python code examples — a broader published language list than PostGate's six, though it's not stated whether all of them are generated from a single OpenAPI contract. |
| White-label branding & custom domain | Every embedded connection environment supports a branded logo, primary color, and a verified custom domain on every plan that enables white-label. See /docs/environments. | No white-label branding, custom domain, or bring-your-own provider app capability is described in public docs; Enterprise plans instead focus on SAML SSO, SCIM, MFA, audit logs, and role-based access. |
| MCP / AI-agent support | A hosted MCP server that creates a draft by default — a tool call must explicitly pass confirm: true to publish. See /docs/sdks-mcp. | A hosted MCP server for AI agents is documented, but the public docs don't specify a tool count or describe a draft-first/confirmation gate before a tool call publishes. |

Why teams switch
Why teams switch to PostGate
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.
