Mixpost

Open-source social media management, honestly reviewed. No per-seat fees, no vendor lock-in — just what you get when you run it yourself.

TL;DR

• What it is: Open-source (MIT Lite edition) social media scheduling platform — think Buffer, but the server is yours and the bill stops at hosting costs [1][4].
• Who it’s for: Marketing agencies, small businesses, and creators who manage 3+ social platforms and are tired of watching their Buffer or Hootsuite invoice climb every time they add a team member or account [1][3].
• Cost savings: Buffer’s Team plan runs $12/channel/month — five channels for three users is roughly $180/month. Mixpost Pro is a $269 one-time payment on a $6–12/month VPS. Year two: you’re paying $72–$144/year versus $2,160 [1][website].
• Key strength: Genuine coverage of all 11 major platforms (including TikTok, YouTube Shorts, Threads, Bluesky, and Mastodon) with unlimited accounts per platform — no artificial caps [1][website].
• Key weakness: Deployment leans on Laravel/Docker familiarity more than some alternatives; the AI writing assistant, advanced queue automation, and approval workflows are locked behind the paid Pro tier; GitHub star count (3,058) is modest compared to the category leaders, signaling a smaller community support base [README][5].

What is Mixpost

Mixpost is a self-hosted social media management platform built in PHP/Laravel. You connect your social accounts, compose posts in a unified editor, and schedule or queue them across up to 11 platforms from a single dashboard. The company — Inovector Digital LLC, founded in Moldova — describes it in the GitHub README as a “Buffer alternative” with “no subscriptions, no limits,” which is the clearest pitch and more honest than the “open source social media management you own” headline on the homepage [README][website].

What separates it from the generic field of scheduling tools:

First, the MIT license on the Lite edition means you can self-host, fork, and even build a client-facing SaaS on top of it without a commercial agreement — the README explicitly calls this out as a use case [README][1]. Second, 11 platform integrations including TikTok, YouTube Shorts, Instagram Reels, Facebook Reels, Threads, Bluesky, and Mastodon — the list that most commercial schedulers either skip or charge extra for [website][1]. Third, the no-per-seat, no-per-account model: you pay for hosting, not for users or connected accounts. An agency running 40 client accounts pays the same as someone running 2 [website][1].

The project sits at 3,058 GitHub stars. That’s not a massive community by open-source standards (n8n has 100K+, Activepieces is at 21K), but it’s an active project with real production users — the website claims 1,000+ businesses across 40+ countries [website].

Why people choose it

The reviews converge on a consistent profile: the people using Mixpost are agency owners and marketing team leads who ran the math on their social scheduling SaaS bill and decided a one-time payment plus a VPS was more rational than a recurring subscription that scales with headcount.

Versus Buffer and Hootsuite. This is the core case. ContentCreators.com [1] frames it cleanly: Mixpost’s no-per-seat pricing is specifically valuable for agencies who would otherwise pay per user per month. An agency managing 20 client accounts with three team members on Hootsuite is looking at $249/month before any add-ons. The AppsMirror review [4] calls out the “no limits or monthly subscription fees” as the headline differentiator — not features, not UI, but the pricing model itself.

Versus Later and Sprout Social. Mixpost covers platforms that Later has historically treated as second-class (Mastodon, Bluesky, Google Business Profile). Sprout Social starts at $249/month for a single seat — it’s not really in the same conversation for small teams, but it’s where some agencies graduate from when they realize they’re managing social content at scale and the tool should cost less than a junior employee’s monthly salary [1][3].

On the data sovereignty angle. StartupHeroes [3] and ContentCreators [1] both flag this. When you route every post through Buffer or Hootsuite, your audience data and publishing history live on their servers. For agencies handling client content in regulated industries, or creators in jurisdictions with data residency concerns, running Mixpost on your own VPS means that data doesn’t move. The Gigazine hands-on test [5] confirms the flip side: getting a platform configured for X (formerly Twitter) requires creating your own Twitter developer app, which adds friction but also means the credentials are yours, not shared through a third-party service.

The OpenClaw integration angle. In early 2026, Mixpost published a skill for OpenClaw (an open-source local AI assistant with 157,000+ GitHub stars) via the ClawHub marketplace [2]. This lets you manage scheduling through conversational commands — “post this tomorrow at 9am to LinkedIn and Twitter” — without opening the Mixpost UI. It’s a real signal that the project is tracking the AI-assistant workflow trend, even if it’s an integration rather than a native feature.

Pricing: SaaS vs self-hosted math

Mixpost Lite (Community Edition):

• Software license: $0 (MIT) [README][1]
• VPS to run it: $6–12/month on Hetzner, Contabo, or DigitalOcean
• What you lose: AI writing, advanced analytics, queue automation, team approval workflows — those are Pro features [1][website]

Mixpost Pro:

• One-time license: $269 [1][website]
• Includes AI assistant, advanced analytics, full queue automation, team collaboration, approval workflows
• You still pay your own VPS hosting — the $269 is for the software, not a subscription

Mixpost Enterprise:

• Custom pricing, contact sales [website]
• Positioned for agencies building client-facing SaaS on Mixpost

Buffer for comparison:

• Free: 3 channels, 10 scheduled posts per channel
• Essentials: $6/channel/month
• Team: $12/channel/month, collaboration features
• Agency: custom pricing

Hootsuite:

• Professional: $99/month for 1 user, 10 accounts
• Team: $249/month for 3 users, 20 accounts

Concrete math for a marketing agency:

Agency running 8 client social accounts with 2 team members. On Buffer Team: 8 channels × $12 = $96/month. On Hootsuite Team: $249/month (even if you’re well under the 20-account cap, you’re paying for the tier). On Mixpost Pro: $269 once + ~$10/month VPS = $389 total in year one, $120 in year two and every year after.

At month 4, Mixpost Pro has already paid for itself versus Buffer. By month 12, you’ve saved $783 versus Buffer Team or $2,720 versus Hootsuite Team. Over three years, the VPS cost is the only recurring line item [1][website].

Caveat: these numbers assume the Pro features you need are covered by the $269 tier and you’re not in enterprise territory. If you need white-label or client billing infrastructure, that’s the Enterprise conversation.

Deployment reality check

The Gigazine hands-on test [5] is the most useful source here because it’s the only review that actually walks through installation rather than summarizing the marketing page.

The Docker path is the recommended route for most users. You grab the official docker-compose.yml from the docs, fill in APP_KEY, APP_URL, and database credentials, run docker compose up -d, and you get three containers: Redis, MySQL, and Mixpost itself. The Gigazine reviewer hit one gotcha: the default port is 9000, not 80, so if you’re expecting to hit the URL directly without a port suffix, you need to either change the config or set up a reverse proxy. Not a showstopper, but it’s the kind of friction that bites non-technical users who followed the guide to the letter [5].

What you actually need:

• Linux VPS with at least 2GB RAM
• Docker and docker-compose
• A domain name and reverse proxy (Caddy or Nginx) for HTTPS
• MySQL and Redis (bundled in the default docker-compose)
• Social platform developer credentials — Twitter/X requires creating your own developer app, which involves a multi-step application process [5]

What can go sideways:

• Twitter/X setup is not trivial. The Gigazine reviewer [5] documents a 6+ step process: create a developer account, submit a use-case description, configure OAuth settings, set permissions to “Read and write.” Twitter’s API tier restrictions (free tier has very limited posting capabilities) may require a paid API subscription separate from Mixpost itself — this is a Twitter constraint, not a Mixpost bug, but it’s worth knowing before you commit.
• The Lite edition’s feature gaps are real. If your use case requires team approval workflows or AI-assisted writing, you need Pro. The Lite edition is a genuine working scheduler for solo operators; it’s not a crippled trial [1][README].
• Laravel stack means PHP hosting requirements. Unlike tools that ship as a single Go binary or minimal Node.js container, Mixpost has a PHP/Laravel dependency tree. The Docker image handles this, but if something breaks and you need to debug, you’re in PHP territory [README].
• Alternative installation as a Laravel package exists for teams already running Laravel apps — but this path has more moving parts than the standalone Docker image [README][5].

Realistic time estimate for a technical user comfortable with Docker: 45–90 minutes to a working instance including social account configuration. For a non-technical founder following a guide: half a day including domain setup, reverse proxy configuration, and Twitter developer app approval (which can take 24–48 hours on its own). The Twitter API friction is the biggest X-factor.

Pros and cons

Pros

• Genuinely MIT-licensed Lite edition. You can self-host, fork, build a client SaaS on top of it, and charge your own clients without a commercial agreement — the README explicitly encourages this use case [README][1].
• 11 platforms including the ones others miss. Bluesky, Mastodon, Threads, Google Business Profile — platforms that most commercial schedulers either don’t support or charge extra tiers to access [website][1].
• Unlimited accounts per platform. No artificial cap on connected profiles. An agency with 30 Instagram accounts pays the same as one with 2 [website][1].
• One-time pricing on Pro. $269 buys the full feature set permanently. No annual renewal, no per-seat escalation [1][website].
• No-per-seat model. Team growth doesn’t trigger a billing event. Add 10 team members — same hosting cost [website][1].
• AI assistant integration for content creation (Pro) — caption generation, tone rewriting, hashtag suggestions that are actually platform-aware [1].
• OpenClaw/ClawHub AI integration for teams using local AI assistants — schedule posts via natural language without opening the UI [2].
• Video content support across TikTok, YouTube Shorts, Instagram Reels, Facebook Reels, including large file sizes [1][website].
• 20+ UI languages — a real feature for international agencies where team members don’t all work in English [website].

Cons

• Twitter/X API setup is a friction wall. Getting X connected requires a developer app, a use-case description approval, and potentially a paid API tier from Twitter — none of which Mixpost controls. Non-technical users will need help here [5].
• AI features and approval workflows are Pro-only. The Lite edition is a solid scheduler but missing what most teams actually need for professional workflows. The $269 Pro price is fair, but the gap between Lite and Pro is wide [1][website].
• Small GitHub community. 3,058 stars means a smaller pool of community-contributed plugins, Stack Overflow answers, and third-party deployment guides compared to more established self-hosted tools. When something breaks, you’re largely on the official docs and Discord [README][3].
• Moldova-based small company. StartupHeroes [3] lists it as a startup with no disclosed funding. That’s fine for now, but it’s a consideration if you’re making a 5-year infrastructure bet. No financial backing data available.
• Analytics depth is unverified. Multiple sources describe the analytics as “visually appealing” but none compare them head-to-head against Buffer or Sprout Social analytics. What you’re getting may be basic reach/engagement data rather than deep audience analytics [1][4].
• Laravel deployment complexity. Not a Docker-native tool in the same sense as simpler self-hosted apps. Debugging requires PHP knowledge [README][5].
• Inbox/engagement feature is still “coming soon.” The website lists an Engagement feature for managing mentions and comments, but marks it explicitly as not yet available. If unified social inbox is a requirement, Mixpost doesn’t have it yet [website][4].

Who should use this / who shouldn’t

Use Mixpost if:

• You’re an agency managing multiple client social accounts and your per-seat tool bill has started feeling like a second payroll.
• You want to publish to all 11 platforms including Bluesky, Mastodon, and Threads without stitching together multiple tools.
• You’re comfortable with (or willing to pay someone for) basic Docker deployment.
• The MIT license matters — you want to embed Mixpost into a client-facing product or resell social scheduling as a service.
• You’re a solo creator or small team where the Lite edition’s feature set is sufficient, and you just want free-forever scheduling without cloud vendor dependency.

Skip it (stay on Buffer or Later) if:

• You need a unified social inbox (mentions, comments, DMs) today — Mixpost’s engagement feature isn’t live yet [website].
• You’re a solo user with fewer than 3 platforms and the Buffer free tier covers your needs.
• You have zero tolerance for command-line setup and no technical help available.

Skip it (pick a more established self-hosted tool) if:

• You need deep community support and a large library of guides and plugins — the 3,058-star community isn’t there yet.
• Your compliance team requires vendor SOC 2 certification or SLA guarantees on the software itself, not just your hosting.

Skip it (use Sprout Social or Hootsuite) if:

• You need enterprise-grade social listening, competitor tracking, or deep CRM integrations baked in.
• Your team’s time cost makes DIY infrastructure more expensive than paying $249/month for a managed solution.

---

Alternatives worth considering

• Buffer — the obvious incumbent. Cleanest UI in the commercial category, solid mobile apps, no self-hosting option. Per-channel pricing makes it expensive at scale.
• Hootsuite — more feature-rich than Buffer (social inbox, basic listening), significantly more expensive, no self-hosting.
• Later — strong for visual/Instagram-focused workflows, weaker on platform breadth, no self-hosting.
• n8n — not a social scheduler, but if you want to build scheduling automation with full code control and you have engineering resources, n8n is infinitely extensible. Overkill for most social media use cases.
• Planka — different category (project management), but worth naming as another example of the “one-time open-source alternative to expensive SaaS” pattern.
• Postiz — newer open-source social scheduling competitor, worth watching. Smaller community than Mixpost currently.

For the core audience — agencies and small teams escaping per-seat scheduling SaaS — the realistic comparison is Mixpost vs. Buffer. Pick Mixpost if you manage enough accounts that the one-time cost makes math sense. Pick Buffer if you want zero infrastructure responsibility and you’re under ~4 channels.

Bottom line

Mixpost is a well-executed, MIT-licensed answer to a specific problem: social media scheduling that doesn’t bill you monthly and doesn’t cap your accounts. The feature set is genuinely competitive — 11 platforms, unlimited accounts, video support, team collaboration, and an AI writing assistant in Pro — and the pricing math is embarrassingly one-sided once you’re managing more than a handful of social profiles. The honest caveats are the small community, the Twitter/X API friction, and the missing unified inbox that’s still marked “coming soon.” For agencies running client accounts or creators managing multiple brand channels, the $269 Pro license pays for itself inside a quarter compared to any mainstream commercial scheduler. The main thing standing between you and switching is a Docker-comfortable afternoon and willingness to navigate Twitter’s developer portal.

If that afternoon is the blocker, that’s exactly the deployment upready.dev handles for clients — one-time setup, you own the infrastructure, no recurring license bill.
