Mixpost is a better fit if you want to run your own social publishing software, reach more networks or manage clients. Flaghand is a hosted desk for a person whose agent prepares posts but cannot authorize publication. Both have an API and MCP; the important difference is what those credentials can do.
Checked on October 26, 2026. Mixpost facts come from its own pricing, Cloud plans, features, integration setup, API, MCP, scheduling and approval documentation. These are public-page checks, not a hands-on trial. Recheck the sources before buying or integrating.
The short answer
- Choose Mixpost for self-hosting, source access, agency workspaces, more networks or an integration that can publish using the permissions you give it. Its managed Cloud option removes server administration.
- Choose Flaghand when your own AI agent writes for you and you want a server-enforced boundary: no agent token can approve, schedule or post. The owner signs the exact posting snapshot with a passkey.
Where Mixpost is better
- A genuine self-hosted choice. Lite is free and open source. Pro and Enterprise are paid, source-available editions, not the same open-source license as Lite. Paid source can be customized for your business, but the pricing page forbids reselling or redistributing that code. Flaghand is a hosted, closed-source product.
- Broader publishing coverage. Paid Mixpost lists Facebook Pages, Instagram, X, LinkedIn personal profiles and company pages, Threads, YouTube, TikTok, Pinterest, Mastodon, Bluesky, Pixelfed and Google Business Profile. Lite lists Facebook Pages, X profiles and Mastodon profiles. Network support is not a promise that every post format works on every network. Flaghand focuses on X and LinkedIn personal profiles; don't choose it for Instagram or company-page publishing.
- Team and client operations. Paid self-hosted plans advertise unlimited accounts, workspaces and users without per-seat charges, plus approval flows and analytics. Separate workspaces can hold separate clients.
- Your hosting choice. Self-hosting gives you operational control, not zero operating cost: you run the server and configure provider integrations. Mixpost Cloud supplies hosting, updates, backups and provider apps. Self-hosted provider setup is once per application, not once per workspace; requirements differ by network.
Pricing and access
Mixpost's self-hosted pricing page lists Lite free, Pro $299 once and Enterprise $1,199 once. Each paid license covers one domain or subdomain and includes one year of updates. Renewal is optional; the fallback license lets you keep the purchased version. The page doesn't quote the renewal price. Running a SaaS requires Enterprise, not Pro. Budget separately for hosting and any provider costs.
Managed Cloud is a different subscription, not those self-hosted allowances:
| Cloud plan | Monthly billing | Yearly billing | Included users and channels |
|---|---|---|---|
| Spark | $29 a month | $249 a year | 1 user, 1 brand; no numeric channel allowance stated in its card |
| Momentum | $49 a month | $419 a year | 1 user, 24 channels |
| Business | $79 a month | $679 a year | 5 users, 48 channels |
| Agency | $149 a month | $1,299 a year | Unlimited users, 180 channels |
Mixpost displays these amounts with a dollar sign and excludes VAT; the cited pages don't identify the dollar currency code. Cloud advertises a seven-day trial requiring a card. We did not start one.
Flaghand is in early access and public sign-up isn't open yet. This guide doesn't quote a Flaghand price; Get access to Flaghand is its current entry point. A self-hosted license, managed team subscription and single-person approval desk aren't interchangeable just because each schedules posts.
API and agent access
Mixpost's current API and MCP docs cover Pro 7 and Enterprise 8. Its official MCP server lives at /mcp on your
instance and supports OAuth or a personal Bearer key. It documents Claude, ChatGPT, Claude Code, Cursor and Codex
connections. Agents can inspect accounts, create posts, schedule or queue them and read analytics within their user's
workspace permissions. It is not accurate to describe Mixpost as having no agent integration.
Its REST docs say a personal key carries the full authority of its creator, without narrower key scopes. MCP applies workspace roles: Viewers read; Members and Admins can write, subject to permissions and approval requirements. Choose the connecting user's permissions deliberately.
Flaghand's live OpenAPI spec and agent documentation describe a different contract:
- Upload media and use
createDraft;post_atproposes a time, not a scheduled job. - Run
checkDrafton the current revision. - Call
requestApproval. The owner reviews and approves inside Flaghand. - Read jobs and use
verifyJobfor the available live check. Asking for approval is not publication.
Flaghand OAuth MCP connectors receive read, drafts, media and request-approval. No API token can approve,
schedule or post, regardless of which agent holds it.
What approval means
Mixpost has real approval controls. Its MCP documentation says scheduling or queueing in an approval-controlled
workspace leaves a post awaiting approval. Its REST scheduling endpoint returns scheduled for a user with approval
authority, or needs_approval without it; immediate posting is also subject to that approval requirement. The REST
approval endpoint can move an eligible post from needs_approval to scheduled when the caller has permission.
Don't mistake permission-based approvals for no approvals, or assume that every API credential is draft-only.
Flaghand freezes the account, time, text, media, alt text and outgoing request into a snapshot. It hashes that snapshot with SHA-256 and records your passkey signature over the hash. Changing the posting content, account or time needs a new approval; the scheduler checks the signed snapshot again just before posting. Its X and LinkedIn previews are drawn to match the real sites. This narrower owner-only authorization is the reason to choose it, not broader platform coverage.
After publication, Flaghand compares available X text, author, reply chain, media count and alt text with the approval. It doesn't verify link destinations or media-file identity, and it has no LinkedIn read-back. Mixpost's analytics and activity tracking serve a different purpose; neither should be mistaken for this limited snapshot comparison.
TikTok slideshows
Flaghand's slideshow API and free TikTok slideshow maker use the same renderer for the preview and output images; approval covers the render hash. Flaghand and TikTok explains its current posting availability during TikTok's review. Mixpost lists TikTok publishing, but its general network list isn't proof of identical photo-slideshow rendering or format support.
Side by side
| Mixpost | Flaghand | |
|---|---|---|
| Core fit | Self-hosted or managed social management for people and teams | Hosted publishing desk for a person and their agents |
| Source | Open-source Lite; paid source-available editions | Closed source |
| Networks | Broader paid coverage, including LinkedIn company pages | X and LinkedIn personal profiles; TikTok subject to review |
| Agent access | Official API and MCP, with user/workspace permissions | API and OAuth MCP with drafting and approval-request scopes |
| Approval boundary | Workspace approval controls; authorized REST callers can approve | Owner's passkey over the exact snapshot; tokens cannot approve |
| Stronger reason to choose it | Hosting control, network breadth, client workspaces | Keep publishing authority out of the agent credential |
