Open-source Sendible alternatives

Postiz helps you plan, automate and analyze social media content from one place. You can use the managed Postiz Cloud, or deploy the open-source edition on infrastructure you control. The application is built with TypeScript and Next.js, uses Redis, and is released under the AGPL-3.0 license.

Beyond the web interface for planning posts across social networks, Postiz exposes a public API and a Node.js SDK, and offers an n8n custom node and a Make.com integration for automation. It also advertises working with AI agents. The README describes an analytics side for reviewing how content performs, along with documentation and video tutorials. The project is aimed at creators, marketers and teams who want scheduling tools they can host themselves.

BrightBean Studio is an open-source social media management platform for creators, agencies, and small businesses. It covers what tools like Buffer, Sendible, and SocialPilot do, planning, composing, scheduling, approving, and publishing posts, but without per-seat, per-channel, or per-workspace limits. It is built with Django, HTMX, and Tailwind CSS and released under the AGPL-3.0 license.

A single multi-workspace dashboard connects to Facebook, Instagram, LinkedIn, TikTok, YouTube, Pinterest, Threads, Bluesky, Google Business Profile, Mastodon, and DEV.to. Features include unlimited organizations, workspaces, and members with role-based access and a client role for outside collaborators, and a content composer with per-platform overrides, version history, templates, and categories. All integrations use the official first-party APIs with your own developer credentials.

The README says every feature is available to every user, with no paid tier. You can deploy it with one-click buttons on Heroku, Render, or Railway, run it with Docker on your own VPS, or use a free hosted version at brightbean.xyz/studio. It suits agencies that manage many client accounts and want to own their social stack.

Mixpost is a social media management platform that you run on your own server, positioned as an open-source alternative to Buffer. It helps brands, agencies and small businesses plan, schedule and publish content from a single place, without a per-seat subscription.

You can bring all your social accounts together, build a content calendar and schedule posts for the times your audience is most active. Team features let you assign tasks, manage permissions and watch team performance. Analytics show audience behavior for each platform based on the data that the networks provide.

Mixpost is built with Laravel, PHP and Vue and is licensed under MIT. The project says it targets enterprises, small and medium businesses, marketing agencies, solopreneurs and e-commerce stores. Its description promises no subscriptions and no limits, since you host it and control the data yourself.
