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.

**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.

## PostLake vs Postiz at a glance

| | PostLake | Postiz |
| --- | --- | --- |
| What it is | Hosted API and MCP server | Open-source app you self-host |
| You run servers | No | Yes, if self-hosting |
| Platform app registration | Managed for you | Yours to obtain and maintain |
| Free tier (no card) | Yes | Self-host free, cloud is trial only |
| Per-agent guardrails | Yes | Not offered |
| Best for | Shipping fast, agents | Teams who want to own the stack |

## 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:

1. **Create a free PostLake account** and connect your social accounts. No developer apps to register, since platform keys are managed for you.
2. **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.
3. **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.
