What happens if I go over 8 hashtags?
That is the record-level tag list. Hashtags typed into the text are just text and spend the 300.
Bluesky Hashtag Counter
Count, de-duplicate and check the hashtags in a Bluesky post against what it actually accepts.
Free, no sign-up, and it runs entirely in your browser. Limits checked 2026-08-31.
How it works
Hashtags are pulled out by the rule every network here shares: a # that begins a word, followed by letters, numbers or underscores, and not made only of digits — so #1 in an ordinary sentence is not counted as a tag.
Duplicates are folded case-insensitively, because #Marketing and #marketing are one tag to the network and two to your character count.
Tags written in styled Unicode are flagged. They look exactly like hashtags and are inert text: no tag page, no reach, and nothing tells you until after you have posted.
Questions
What happens to the text I paste in?
Nothing. There is no server behind these pages — the tool is JavaScript running in your tab, so what you type stays in the browser and is never sent anywhere, by us or by anyone else.
Is it really free, and is there a catch?
Free, with no sign-up, no limit and no watermark. These tools cost us nothing to run because they run on your computer rather than ours. We build them because the people who need them are the people who might eventually want the product they sit next to — that is the whole arrangement, and it does not require anything from you.
The same tool, other networks

Every fix on this page is one you have to remember every time you post. Influenar drafts for Bluesky with its rules already applied, and holds the result on a calendar you can argue with before anything publishes.
