#prasar

Write once, post to X and LinkedIn from the terminal. One editor with a live preview of how each network will show your post, drafts, a schedule, and an AI agent that can draft posts for you (you approve every one). Free: LinkedIn through its free API, X through its own share page with one click.

Prasar (प्रसार) is Sanskrit for "spreading out, broadcast".

#What it does

• One editor, two previews. Write on the left; on the right, the post as X shows it (with X's own count: links are 23, CJK and emoji 2) and as LinkedIn's feed shows it (folded where "…see more" cuts it), each with a meter that turns yellow near the limit.
• Threads. A post longer than X's 280 becomes a thread, split at sentence ends and numbered 1/3, or split it yourself with a line holding only ---. On LinkedIn those lines become paragraph breaks, so the same text is one post there.
• LinkedIn posts by itself through its free API, images included, and #words become real hashtags.
• X with one click: prasar opens X's share page with the post filled in, you press Post. Images go to your clipboard to paste. Why: X's API costs money per post since 2026 (ADR 2).
• Drafts, a schedule, history: tabs for Compose, Queue (waiting and scheduled), Drafts and Posted, with each post's links.
• Never lose a post: closing the screen keeps what you wrote as a draft.
• Agents draft, you decide: prasar mcp lets Claude Code (or any MCP agent) check, draft and propose posts; every one waits for your approval in a popup, where you can edit it (ADR 3).
• Looks like the rest of your terminal: rounded boxes and key caps like sandesh, pattan and nauka, in your varna theme's colours (Catppuccin Mocha without it), changing live.

#Install

With kosha:

kosha install prasar

Or with the installer, which downloads the release binary into ~/.local/share/prasar (or builds it with Go) and links ~/.local/bin/prasar:

curl -fsSL https://raw.githubusercontent.com/Theyashsawarkar/prasar/main/install.sh | bash

From source: make && make install (Go 1.26+).

As a tmux plugin (TPM), prefix B opens it in a popup:

set -g @plugin 'Theyashsawarkar/prasar'

The plugin runs the prasar on your PATH, or builds its own copy with Go the first time.

Optional: wl-clipboard (Wayland) or xclip (X11) for images on X and copying links, notify-send (libnotify) for notifications, secret-tool (libsecret) to keep the LinkedIn sign-in in your keyring.

Try it first without any account: prasar demo runs it with a fake LinkedIn in a throwaway folder (nothing is posted, X isn't opened).

#Set up LinkedIn

prasar posts to LinkedIn through an app of your own: free, self-serve, about two minutes, once (ADR 4).

prasar auth linkedin --setup

It walks you through it:

1. At linkedin.com/developers/apps/new create an app: any name, a LinkedIn page as its company (LinkedIn needs one; one you create works) and a logo.
2. On the Products tab add Share on LinkedIn and Sign In with LinkedIn using OpenID Connect (both approved at once).
3. On the Auth tab add http://localhost:8723/callback to "Authorized redirect URLs", and copy the Client ID and Primary Client Secret into prasar.

Then your browser opens on LinkedIn's sign-in. LinkedIn's sign-in lasts 60 days and can't be renewed silently: the screen's top right shows the days left, turning yellow in the last week, and L (or prasar auth linkedin) signs in again.

prasar posts to your personal profile. Company pages need LinkedIn's review and aren't supported.

#Posting to X: one click

X has no free API any more, so prasar never logs in to X. When a post goes out:

1. X's share page opens in your browser with the post filled in (the first image, if any, is on your clipboard: Ctrl+V pastes it).
2. You press Post there.
3. Back in prasar, press Enter. Paste the post's link first if you want it kept; for a thread, the link makes the next part a reply to it.

Esc leaves it for later (it waits in Queue, o opens it again); Ctrl+K skips X for that post. A scheduled X post can't go out without you: at its time a notification offers to open it.

#The screen

prasar (or prefix B in tmux) opens on Compose, in the editor:

• Compose: the editor, the "Post" box (where it goes: Ctrl+X / Ctrl+L; when; images), and the X and LinkedIn previews. Under 100 columns the previews give way to their counts.
• Queue: what's waiting on you (an agent's post to approve, an X post to click, a LinkedIn post that failed) and the schedule, soonest first, with the selected post in full below. The footer shows the keys for that post.
• Drafts: posts you kept; e edits one, p posts it, t schedules it.
• Posted: what went out, with its links; v opens one, y copies it.

The top right says who LinkedIn posts as (and days left) and that X is one click. Tabs count what's in Queue and Drafts.

#From the shell

prasar post "Shipped it #golang"                 # both networks (or config's `networks`)
prasar post --linkedin "Only on LinkedIn"
prasar post --x --image shot.png "With a picture"
prasar post --at "fri 6pm" "Later"               # scheduled
prasar post --draft "Not yet"
echo "From a file" | prasar post -               # text on stdin
prasar check "Will this fit?"                    # X count and thread, LinkedIn count and fold
prasar list [draft|scheduled|approval|ready|posted|failed]
prasar approve [ID]                              # an agent's post (the oldest waiting)

Times (--at, Ctrl+T, t) read the way people write them: in 2h, tomorrow 9am, fri 6pm, next tue 10:00, tonight, 3 nov 10:30, 2026-11-03 18:00. A day without a time means 9:00.

#The schedule

Scheduled posts go out while prasar runs (the screen, prasar mcp), or at any time with the background service:

prasar service install      # ~/.config/systemd/user/prasar.service, started now and at login
journalctl --user -u prasar -f

At a post's time, LinkedIn goes out by itself and you get a notification; X waits for you (the notification's "Open in browser" opens it). A post is claimed before it's sent, so the screen, the MCP server and the service never publish one twice.

#For AI agents (MCP)

claude mcp add --scope user prasar -- prasar mcp --requester "Claude Code"

Agents never post on their own, and are told X needs your click. What they did is logged in ~/.local/state/prasar/agent.log.

#Configuration

~/.config/prasar/config.toml (written by prasar auth linkedin --setup, private to you):

networks = ["x", "linkedin"]   # ticked in a new post

[linkedin]
client_id = "..."
client_secret = "..."
port = 8723                    # the redirect: http://localhost:<port>/callback
version = "202607"             # LinkedIn API version (YYYYMM); LinkedIn retires each after about a year

[x]
name = "Your Name"             # shown in the X preview (default: your LinkedIn name)
handle = "you"                 # shown as @you in the X preview

tmux plugin options (set before TPM's run line):

#How it works

One Go binary: the screen (Bubble Tea), the CLI, the MCP server and the service share internal/app, which keeps posts in SQLite and moves them between draft, approval, scheduled, ready (X waits for your click), posted, failed, cancelled and declined only through checked transitions. internal/post knows each network's rules (X's weighted count and thread splitting, LinkedIn's "little text" escaping and hashtags), internal/linkedin the API, and internal/fake a fake LinkedIn for the tests and prasar demo. Decisions are recorded in docs/adr.

#Troubleshooting

• LinkedIn: "refused the sign-in" — the 60 days ran out or the app changed: prasar auth linkedin.
• LinkedIn: "the app may not do this" — add the Share on LinkedIn product to the app.
• LinkedIn: "retired this API version" — set linkedin.version in config.toml to a recent month (YYYYMM, a few months back).
• "can't listen on port 8723" — something else uses it: set linkedin.port and the app's redirect URL to another port.
• X: the image isn't there — X's share page can't take images: paste it (Ctrl+V); prasar copied it when the page opened (needs wl-copy or xclip).
• A scheduled post didn't go out — nothing was running at its time: prasar service install. prasar doctor checks it all.
