A post for each network

The form takes the product name, a one-line tagline, the URL, where you are launching, an optional offer, and a tone. Plain keeps the draft to the facts. Excited is warmer, and it still skips the firework emoji and the 'thrilled to announce' opener. Each box is a draft you can paste. Edit a box if you want to cut a line before you copy it.

The page does not ask you to sign up, and it does not send the draft anywhere. The text stays in this browser. Copy uses the clipboard on your device.

Where the limits come from

X's counting-characters page caps a post at 280 characters. A URL counts as 23 characters because X wraps it with t.co, short or long. Emoji count as 2, including a skin-tone emoji and a family emoji. CJK characters count as 2. The counter uses the weights in the twitter-text v3 config that page links to: code points through U+10FF count as 1, a short list of punctuation marks count as 1, and the default weight is 2. A link is counted as a URL when it starts with http://, https://, or www. Text is normalized to NFC before that count, which is what that page describes.

Bluesky's intent-links page says the post length limit is 300 characters, more precisely 300 Unicode grapheme clusters. The link is part of the post and counts in full. This page counts graphemes against 300.

Threads' developer docs limit a text post to 500 characters and say emoji are counted as the number of UTF-8 bytes. A normal letter still counts as one. An emoji counts as the bytes in that emoji, so a single emoji is usually 4, and a joined sequence is longer. LinkedIn Help says a post can contain up to 3,000 characters and, if you go past that, points you to an article instead. LinkedIn does not publish a separate weight for links, emoji, or CJK, so this counter counts graphemes and counts the URL in full.

Mastodon's posting guide says the default character limit is 500. Links that start with http:// or https:// count as 23 characters, whatever their length. In a mention written as @name@server, only the @name part counts and the domain does not. The guide calls 500 the default because a server can run a different cap. This counter uses 500. A post that fits here can still be over the limit on a server that set a lower number.

Limits checked October 2026. The source for each number is linked under the draft and in the table below.

Keep the post specific

The drafts name the product, the place, and the tagline, then the link. They do not invent a customer count or a launch rank. If you add an offer, it is copied in as a 'Launch offer' line and it counts toward the limit. A long tagline is the usual reason an X or Bluesky draft goes over. Shorten that line, or edit the draft in the box, until the counter is inside the limit.

Directory forms have their own length checks. The launch copy character counter measures a tagline and a description for those forms. The launch week planner lays out a week of submission dates. The drafts here are the social posts, not the directory form.

What the subscription does not change

Premium Launcher is $300 per month for one license key on Aura++, Earlyhunt, Indiehunt, Uno Directory, MakerHunt, and SideHunt. The license does not publish these drafts, and it does not raise the character limit on X, Bluesky, Threads, LinkedIn, or Mastodon. The subscription is on pricing.
