## Postiz

Postiz puts scheduling and AI agents in the same tool. You connect the channels you already use, compose once, and publish to every selected network on the schedule you choose, previewing everything on a visual calendar before it goes live. What makes it different is how agents plug in: through an MCP server and CLI, assistants such as Claude, ChatGPT, Claude Code, Codex, Cursor, Gemini, Grok and OpenClaw can draft, queue, and even read back performance data. You type a goal like "schedule these clips to TikTok and Instagram, eight hours apart, all week" and the agent executes it as drafts or live posts.

For teams, Postiz adds the operational pieces: invite collaborators, assign posts, keep multiple channels organized in one workspace, and use auto actions that trigger follow-up posts, likes, or comments when a post hits a milestone such as 100 likes. Analytics show which posts and channels perform best so you can double down on what works. The platform is also friendly to builders and automation: a public API, OAuth2, and an SDK let you ship your own posting app, while native integrations with n8n and Make.com (plus Zapier) let workflows draft, approve and publish hands-free.

Postiz is widely used by AI-first marketers, developers, and automation teams, and it is known for being open source, which many users credit as their entry point before subscribing to the hosted service. A built-in Canva-like image editor and AI image generation cover the visual side of a post, and Discord is available for support.

**Pricing & Plans:** Free trial and paid plans. A 7-day trial costs $0, after which paid subscription tiers apply; custom/enterprise arrangements are available on request. Check the official pricing page for current per-plan limits.

- **One calendar for 30+ networks:** Write a post once and publish to every selected channel, previewing the whole schedule visually before it goes out.
- **Agentic scheduling via MCP and CLI:** Claude, ChatGPT, Claude Code, Cursor, Grok, OpenClaw and others draft, schedule and analyze posts programmatically.
- **Team collaboration:** Invite teammates, assign posts, and keep every channel and approval organized in a shared workspace.
- **Auto actions:** Set a milestone like 100 likes and Postiz automatically posts, likes, or comments to keep engagement going.
- **API, SDK and automations:** Build posting apps with OAuth2 and the public API, or wire workflows through n8n, Make.com and Zapier.

**Strengths:** Agents can post directly through MCP and CLI, which most competitors make hard; Supports a very large number of channels including niche ones like Bluesky, Mastodon and Lemmy; Open source with a public API and SDK for building on top; Calendar preview, auto actions and analytics in one workspace

**Limitations:** Per-platform formatting quirks still require review before publishing; Full automation depends on learning the CLI or MCP setup

## Linkzelo (formerly Solobuilderhub)

Linkzelo is a browser extension for people who use LinkedIn as a relationship-building channel and want to engage more often without sounding robotic. Once installed, it adds AI suggestion controls to the LinkedIn interface so you can ask for a comment or reply on the post you are currently viewing, choosing a target persona and tone before generating.

The tool leans on personalization rather than bulk automation: you describe the persona you want to sound like, pick a tone, and the extension returns a draft you can edit before posting. A secondary feature generates memes from a post, which can be useful for lighter, more shareable engagement in a feed that is otherwise full of polished corporate posts.

Privacy positioning is part of the pitch — the listing states data is handled with local storage and that information is not sold to third parties. As with any LinkedIn helper extension, users should review the permissions the extension requests and confirm behaviour against LinkedIn's own terms of service before relying on it daily.

**Pricing & Plans:** Free to install with optional in-app purchases listed in the Chrome Web Store.

- **AI comment and reply generation:** Generate contextual comments and replies for the LinkedIn post you are viewing, with a draft you can edit before publishing.
- **Persona and tone targeting:** Tell the AI who you want to sound like and which tone to strike, so output fits a specific professional voice.
- **Meme generation from posts:** Turn a feed post into a meme image for lighter, more shareable engagement.
- **In-page LinkedIn integration:** Suggestion controls appear inside LinkedIn in the browser, so you do not have to copy text into a separate AI tool.
- **Local, private data handling:** The developer states that data is kept in local storage and is not sold to third parties.

**Strengths:** Adds AI drafting directly inside LinkedIn, so no tab switching; Persona and tone controls make output feel less generic; Meme generation is an unusual extra for feed engagement; Free to install, with paid options only if you want them

**Limitations:** Small user base and only a handful of ratings, so community feedback is limited; Third-party LinkedIn extensions carry inherent account-risk and policy considerations; No standalone web app — you must be in a Chromium browser to use it
