PostLake vs Postiz

The Postiz alternative
with nothing to host.

Postiz is open source and genuinely good, and you can run it yourself. That is its biggest strength and its biggest cost. PostLake is the hosted answer: no server, no upgrades, no platform apps to register, and a free tier with no card.

No card for the free tier · 20 credits a month · full MCP access

Short version: choose Postiz if owning and running the software matters more than the time it takes. Choose PostLake if you would rather ship the feature this afternoon and never think about the infrastructure.

Why developers & agents pick PostLake

Start free, pay for what you post

A free tier with 20 credits, no card. Then usage-based credits, one per post (X costs more, since X is the only network that charges us). Low-volume projects pay a fraction of a flat monthly seat.

Agent-first, not agent-also

A hosted MCP server built for agents, idempotency keys so a retrying agent never double-posts, and one normalised response an agent can reason over. Built for Claude, ChatGPT, Cursor and any MCP client.

Managed keys, no app setup

PostLake manages every platform connection for you, X included. No developer apps to register, no per-platform review queues to babysit. Connect an account and post.

One response for every network

Publish to many accounts in one call and get back a single normalised shape, one post id and a per-target result, so you never branch your code per platform.

Where Postiz is the better fit

We'd rather be honest than oversell. Postiz is the better choice when:

Ownership matters. It is open source. You can read it, change it, and run it on your own infrastructure forever without a vendor.
You want the widest channel list. Postiz covers a longer tail of networks than we do, including several we have no plans for.
Data residency or compliance means the content cannot leave your own servers. Self-hosting answers that in a way no hosted service can.

A worked pricing example

The money is not the interesting part. The time is. Self-hosting means a server, a database, and your own developer app on every network you want, each with its own review.

Scenario: getting to your first published post	PostLake	Postiz
Setup	Connect an account and post	Deploy, configure, register apps
Platform approvals	Handled for you	Yours to obtain per network
Ongoing	Nothing to maintain	Updates, uptime, key rotation

If you enjoy running infrastructure, Postiz is a strong piece of software and self-hosting is free. If your goal is a working integration today, the hosted path removes the part that actually takes the weeks. (Verify current figures on Postiz's pricing page before relying on them, July 2026.)

Switching from Postiz

If you are moving off a self-hosted instance:

Create a free PostLake account and connect your social accounts. No developer apps to register, since platform keys are managed for you.
Point your integration at PostLake. Use the REST API with a Bearer key, or connect your AI agent to the hosted MCP server over OAuth.
Map the response. PostLake returns one normalised shape, a post id plus a per-target result, so most integrations need only light changes.

Common questions

Is PostLake open source?

The MCP server and agent skills are public on GitHub. The hosted API is not, and self-hosting is not something we offer. If running it yourself is a requirement, Postiz is the honest recommendation.

What does self-hosting actually cost me?

Nothing in licence fees, and real time in setup and upkeep. The larger cost is usually the platform approvals: with a self-hosted instance you register and maintain your own developer app on every network.

Which is better for AI agents?

PostLake, on current shape. Agents authorise over OAuth so no key is pasted into a chat, and you can cap what each agent is allowed to do.
