myna

Post to every network
from your terminal.

myna is a social media manager that lives where you already work. Connect an account, write once, and it goes everywhere — tailored to each network's limits, not truncated to the smallest one.

curl -fsSL https://mynaposter.com/install.sh | sh

A single binary with its runtime built in — no Bun, Node or npm needed. Linux, macOS and Windows. Already have a package manager? bun add -g @profullstack/myna. Read the script before you pipe it, as you should with any of these.

25 networks. Credentials encrypted on your own machine. MIT.

The right pane counts the way each network counts. X reads one character higher than the others here because it bills every URL at 23 characters regardless of length.

One post, every network

Character limits, URL weighting, threads where they exist and truncation where they do not. A 900-character post becomes a four-part thread on Bluesky, one post on Mastodon, and an article on your blog.

Schedule and forget

myna schedule "tomorrow 9am" queues it. The scheduler sends it while the TUI is open, or run myna run as a daemon and close the terminal.

Read back

Home timelines, mentions, per-post engagement, and a history of exactly what landed and what failed — with the error, not a shrug.

Logging in, honestly

Most tools are vague about this, so here it is plainly. myna login <network> asks for whatever that network actually accepts.

8 take a real password

Bluesky, Reddit, Mastodon, Pixelfed, Lemmy, Matrix, Mattermost, WordPress.

You type a username and a password and you are in. Use an app password where the network offers one.

7 need a browser sign-in

X, Facebook, Instagram, Threads, LinkedIn, Pinterest, TikTok.

Not a limitation of myna. These removed password APIs years ago, and scraping a login session breaks without warning and violates their terms. myna does a normal OAuth round trip through your browser instead.

Two things worth knowing before you plan a workflow. Facebook and Instagram cannot post to a personal profile at all — Facebook needs a Page you administer, Instagram a Business or Creator account linked to one. And Reddit script apps and Mastodon's password grant are both refused on accounts with two-factor enabled; those fall back to a token.

A TUI and a CLI, same commands

Every slash command in the TUI is also a subcommand, so anything you can do by hand you can put in a script or a cron job. 

myna                                  # the TUI
myna login bluesky                    # connect an account
myna post all "the release notes are up"
echo "shipping today" | myna post bluesky,mastodon
myna link https://example.com/post --to all
myna schedule "tomorrow 9am" "good morning" --to mastodon
myna accounts --json | jq '.[].id'

An optional writer

Paste a link and myna reads the page and drafts a post about it, with hashtags that suit each network and none where they would look out of place. It drafts; you edit; you post. It never posts on its own.

Anthropic by default, or OpenAI, or a local model through Ollama. Turned off entirely unless you configure a provider — myna is a perfectly good poster without it.

Infographics with real text

The model picks the copy; myna renders the graphic. The words on the image are exactly the words in the copy.

This is not a stylistic choice. Ask an image model to draw a chart with labels and it rewrites the labels: invented figures, misspelled names, quotes nobody said. Separating the two removes that failure rather than hoping against it.
