Sendible is built around managing several clients: workspaces, social profiles, team access, approval workflows and reports. Flaghand is a narrower publishing desk: your own AI agent prepares X and LinkedIn posts, and an owner approves the exact account, content and time with a passkey before anything goes out.
Checked on October 26, 2026. Sendible facts come from its own pricing page, USD monthly pricing frame, agency setup guide, client setup guide, supported platforms, custom reports guide, white-label setup guide and SSO page. Prices and features can change. This is a public-documentation comparison, not a signed-in product test. The help articles blocked direct automated retrieval, so their facts were checked against indexed text from those official pages.
The short answer
- Choose Sendible if you manage several clients' calendars, need Facebook, Instagram or LinkedIn Pages, collect client approvals and deliver reports. Its workspaces and unlimited users suit agency collaboration.
- Choose Flaghand if the work is X and LinkedIn personal-profile publishing, your own agent writes the posts, and you want the server to refuse posting without a passkey-approved snapshot. It is not a replacement for client reporting, broad network coverage or a white-label agency dashboard.
What Sendible costs
Sendible's official pricing frame displayed these USD prices with monthly billing. The main pricing page supplies the workspace and profile counts and lists unlimited users on every plan:
| Plan | Billed monthly | Included workspaces | Included social profiles | Users |
|---|---|---|---|---|
| Core | $35 a month | 1 | 6 | Unlimited |
| Plus | $99 a month | 3 | 18 | Unlimited |
| Premium | $199 a month | 7 | 42 | Unlimited |
| Elite | $299 a month | 15 | 90 | Unlimited |
| Enterprise | $750 a month | 50 | 300 | Unlimited |
The main page advertises a 15% saving with annual billing. We could not confirm each plan's exact annual charge from the publicly retrieved pricing, so the figures above are monthly-billed prices, not annual equivalents. Additional workspaces add six profiles each; the retrieved page did not expose their price. White labeling is a paid add-on on Elite and Enterprise, not included in the base prices above.
Assignment and approvals start on Plus; custom branded reporting starts on Premium. For a freelancer with three clients and six profiles each, Plus supplies three workspaces and 18 profiles. Seven clients with the same setup fit Premium's seven workspaces and 42 profiles. Those are capacity examples, not a requirement that every client use a workspace or a quote for extra profiles. Unlimited users does not mean unlimited social profiles.
Flaghand is in early access: public sign-up isn't open yet, and its pricing isn't public. The access link below goes to the waitlist, not to an immediately available paid agency plan.
Where Sendible is better
- More client networks. Sendible lists Facebook Pages, Instagram, LinkedIn personal profiles, company and showcase pages, X, TikTok, YouTube, Threads, Bluesky and Google Business Profile, plus WordPress publishing. Its help lists automated Instagram publishing for Professional Business and Creator accounts. Not every format is automatic: the pricing page describes reminder/mobile completion for Instagram carousels containing video. Network support does not imply identical analytics, inbox or format support everywhere.
- Client workspaces. Separate workspaces and profile allowances help organize several clients, and every plan lists unlimited users. Approval settings let you assign a reviewer to a client or workspace. Flaghand has owners and editors, with only owners approving; it has no equivalent white-label agency client portal.
- Reports. Core has standard reports. Premium adds custom branded reporting, with two custom reports per workspace; Elite and Enterprise list three. Sendible documents PDFs, live report links and one-time or recurring report emails. Check the chosen plan for each sharing or delivery option: the retrieved feature table did not preserve every inclusion marker. Flaghand has X performance numbers for best-time learning and an agent can inspect top X posts; it has no client report builder, competitor reports or LinkedIn analytics.
- Your agency's branding. Elite and Enterprise offer a paid white-label add-on. That is more than adding your logo to a report, and more than Flaghand's owner/editor publishing workflow.
Flaghand publishes to X and LinkedIn personal profiles, not LinkedIn company Pages. Its public TikTok posting is still in TikTok's review; see Flaghand and TikTok. If those other client networks are essential, Sendible's broader coverage is a concrete reason to choose it.
API and MCP: do not confuse SSO with publishing
Sendible's white-label setup documentation says, "We currently only support SSO integration via our API." Its SSO page describes API-based SSO on Enterprise, with application/use-case and security review before key access. That is a way to sign users into an integrated product, not evidence of a generally available API for creating drafts, scheduling posts or retrieving campaign analytics.
We did not find an official Sendible MCP server in the public pages and official-domain searches checked for this guide. That does not prove a private integration is unavailable, or that an integration could not be built. If agent access is essential, confirm the actual supported publishing operations and permissions rather than assuming an SSO API key provides them. We did not request a key or contact Sendible.
Flaghand exposes a public agent manual, OpenAPI specification and hosted MCP server. Agents can upload media, create and check drafts, and request approval. No API token scope can approve, schedule or post. OAuth-connected agents receive drafting permissions, not an owner's authority. The boundary is enforced on the server, not only written in the agent's prompt.
Does a person approve every post?
Sendible can require approval, but the exact workflow matters. Its agency setup guide describes a workspace's Post approver: "Adding someone here means that they will need to approve every post on that workspace before it is sent." That is stronger than a preview link with optional comments, and should not be dismissed as having no approval enforcement.
The client setup guide separately describes Needs approval before publishing for a user and an Approved by reviewer. It also documents an administrator exception: when an administrator switches into the client's dashboard to create a post, "you will not be forced to send the post for approval; however, your client will." The checked sources do not resolve whether that exception also applies to the separate workspace Post approver setting. Do not turn these two settings into a blanket claim that Sendible either always requires approval or always lets an administrator bypass it. Confirm the configuration and user roles for the client's actual workflow.
In Flaghand, an owner approves in the desk with a passkey. The approval freezes the account, time, text, media and alt text into a snapshot, records the passkey signature over its hash, and the scheduler checks it again immediately before posting. A change to the posting content, account or time requires new approval. An owner can approve several posts as one plan; they do not need to be online at each scheduled time. This owner may be an agency operator: owner approval is not automatically approval by the agency's client.
After it posts
The Sendible pages checked here describe scheduling, approval and performance reporting. They do not document comparing a live post with a passkey-signed snapshot. That is not a claim about every internal check Sendible may perform.
Flaghand reads X posts back and compares normalized text, author, reply chain, media count and available alt text with what was approved. It does not verify link destinations or media-file bytes. LinkedIn posts are not read back, so Flaghand does not offer that same verification on LinkedIn. A report of reach or engagement is a different service from checking whether a post matches its approval; an agency may need both.

Bringing client drafts
If you already have a CSV or JSON file, Flaghand's migration recipe uses its own column format, so map the fields first. It creates drafts with proposed times, not approvals or publishing jobs. This is a file-based recipe, not a one-click Sendible migration. Existing schedules in another tool remain active until you change them there; importing a draft does not cancel the original.
For several clients, confirm workspace ownership and which person's passkey gives the final decision before choosing a tool. A workspace boundary is not a substitute for a client's review process or a monthly reporting service.
