| License & source access | AGPL-3.0. Full source public on GitHub; you can read, fork, and self-host it. | Proprietary. Source is not published; no self-hosted version exists. | Proprietary. Source is not published. |
| Deployment model | Self-host for free (Docker, Postgres, Redis, a worker fleet you run) or use Postiz's own managed cloud. | Managed, multi-tenant API — call an HTTPS endpoint, PostGate operates the queues and workers. | Managed API — no infrastructure to run. |
| Starting price & free tier | Free forever if self-hosted. Managed cloud from $29/mo (Standard, 5 channels) up to $99/mo (Ultimate, 100 channels) — trial only, no free cloud tier. | Free sandbox plan, no card required. Paid plans start at $4.00/mo. See /pricing. | No permanently free plan; a 28-day free trial. Paid plans from $149/mo (1 profile) to $599/mo (30 profiles), custom Enterprise above that. |
| Who runs platform-app review & uptime | You do, if self-hosting: your own Meta/TikTok/LinkedIn app approvals, your own monitoring and incident response. | PostGate operates the shared infrastructure; bring-your-own provider apps available on the white-label plan. See /whitelabel. | Ayrshare operates the infrastructure; bring-your-own API keys documented for X (Twitter), with broader coverage described as planned. |
| White-label branding & custom domain | Not a built-in product; a self-hoster can put their own domain in front of their own deployment, but there's no hosted, verified white-label connection flow. | Branded logo, primary color, and a verified custom domain on every plan that enables white-label. See /docs/environments. | Branded OAuth linking page from the Launch plan ($299/mo); full custom CSS/favicon/footer gated behind a separate add-on. |
| SDKs & API contract | REST API included on cloud tiers and in the self-hosted app; no generated multi-language SDKs published. | Generated clients for six languages — Node.js/TypeScript, Python, Go, Ruby, PHP, .NET — from one OpenAPI contract, plus a hosted MCP server. See /docs/sdks-mcp. | SDKs for Node, Python, Go, a CLI, and a native MCP server. |
