Publish prepared content without breaking each channel's rules.

RostrumPost turns prepared text and media into native variants, checks every platform, and publishes only where the connection allows.

From one source to published, in four steps.

The same path whether a person clicks through it or an agent drives it over the API.

1

Source

Bring prepared text and media, or pull from your content studio over the API.

text, media, API

2

Native variants

RostrumPost adapts the message to each platform's format, length, and media rules.

3

Preflight

Every variant is checked for length, media, duplicates, and connection capability.

4

Publish or schedule

Publish where the connection allows, schedule the rest, hand off the assisted ones.

Preflight

Know before you publish.

Most tools let you queue a post and find out it failed later. RostrumPost checks each platform's real requirements first, then shows what is ready, what needs a fix, and what needs a native finish.

Length and title limits

Captions and titles are validated against each platform's limits before they reach the queue.

Media readiness

Required media, formats, and video for Shorts are confirmed, not assumed.

Connection capability

Direct, assisted, or pending platform review is shown per channel, so nothing fails by surprise.

Duplicates and account limits

Duplicate content and one-account-per-platform limits become actions, not errors after the fact.

Ready

X direct, 142 / 280 characters
LinkedIn direct, image attached
Bluesky direct, 188 / 300 characters

Needs a fix

YouTube Shorts attach a video to continue
Instagram waiting on platform review

Native finish

TikTok, Threads prepared here, finish in the app

Approvals without the back and forth.

Send a public approval link to a client or teammate. They review the exact native variants, approve or request changes, and the record stays in sync with internal review.

Public link, no login

Reviewers open one URL and see the real per-platform variants.

Superseded on edit

Editing a variant marks the previous approval as superseded automatically.

X variant · draft

New release notes are live. Prepared once, adapted per channel, checked before anything goes out. Which platform would you adapt first?

Internal review and the public portal share one record.

Agents propose. Humans approve.

A REST API, a CLI, an MCP server, and an agent Skill share one authorization model. Give an agent a draft-only key, require approval before anything publishes, and read every action in the audit log.

rostrum cli

> preflight: 2 direct, 0 blocking
> variants ready: x, linkedin

$ rostrum publish preview <variant_id>
> status: ready
> requires scopes: jobs:write + publish:write
> awaiting human confirmation

Scoped keys

Grant only the scopes a workflow needs, from read-only to publish.

Draft-only mode

Agents can compose and preflight without the ability to publish.

Approval required

Gate publishing behind human approval per workspace.

Audit log

Every key, run, and mutation is recorded and exportable.

A calendar that behaves like a queue.

Scheduled, published, failed, and needs-native-finish are distinct states, not one ambiguous status. Filter, retry, reschedule, or cancel in bulk.

Straight answers about platform limits.

Can RostrumPost publish to every platform automatically?
No, and that is the point. X, LinkedIn, Bluesky, and YouTube Shorts publish directly once connected. Threads, Instagram, and TikTok are prepared in RostrumPost and finished natively, because their APIs require it. Preflight shows the mode per channel before you publish.
What does assisted handoff mean?
The native variant is built and validated here, then you complete the final step in the platform when its API does not allow direct publishing. Nothing fails silently in the queue.
Are my platform credentials stored safely?
Credentials live in an encrypted vault, and external publishing stays off until you enable it per provider. By default the product runs with safe mock providers, so you can try the full flow without sending anything live.
Can I drive RostrumPost from code or an agent?
Yes. The REST API, CLI, MCP server, and agent Skill share one scoped authorization model, with draft-only keys and approval gates. Publishing and scheduling require explicit scopes plus human confirmation.
Is there a free way to try it?
Yes. Run a local workspace with mock providers at no cost, connect a real channel when you are ready, and move to a paid plan when you publish at volume.

Publish with fewer surprises.

Turn prepared content into native variants, preflight every channel, and publish only where the connection allows.
