Clipboard history that works with developer content. Format JSON, decode JWTs, transform curl, and convert between formats - fully local, secrets stay safe.
StackClip is a clipboard manager built for developers who work with real data - not just plain text.
If you regularly copy JSON, JWTs, curl commands, SQL, config, or snippets, you’ve felt the friction: losing important data, reformatting it manually, or switching tools just to reuse it.
StackClip fixes that.
It captures what you copy, understands what it is, and helps you reuse it instantly - without leaving your workflow.
FEATURES
• Built for technical data - JSON, JWTs, curl, SQL, YAML, env values, code snippets, and more
• Smart classification - Automatically detects what you copied so you can filter and act on it instantly
• Contextual actions - Format, minify, decode, and transform data in one click
• Fast search - Find clips by content or type in seconds
• Snippets - Save and reuse commands, queries, and boilerplate
• Transform pipelines - Chain actions into reusable workflows
• Secret masking - Sensitive values stay hidden until you choose to reveal them
• Keyboard shortcuts - Access history, paste recent clips, and move faster without breaking flow

# What's New in StackClip 0.9.0
The longer your clipboard history gets, the harder it is to find what you need. 0.9.0 is the discovery release - faster search, saved filters, tag visibility in the list, and a dashboard that now shows what's actually in your history.
## Full-Text Search
Search is now powered by SQLite FTS5. The old LIKE-based search was fine up to a few hundred clips. FTS5 is indexed, so the same query over thousands of clips returns in under 50ms. Partial-word matching still works - searching "func" still finds "function". Regex mode continues to use the original path.
## Saved Searches
Set up a filter combination you use regularly - a tag, a content type, a source app - and save it with the bookmark icon next to the search bar. Saved searches appear as pills above the clip list. Click one to restore your exact filter state. Hover to reveal the delete button. Drag to reorder.
## Tags on Clip List Items
Tags are now visible without opening the detail panel. Each clip in the list shows up to two of its tags as small chips below the preview text. If a clip has more than two, the remainder appears as a +N chip. Clicking a tag chip immediately filters the list by that tag.
## Duplicate Detection
When StackClip promotes a clip over an older duplicate, the new clip now tells you. A banner in the detail panel shows whether it is an exact copy or a reformatted version, and offers a "View original →" link that scrolls to the earlier clip. Promoted clips also show a subtle ↑ badge in the list.
## Dashboard: Tag Distribution and Stale Clips
The dashboard now shows a "Top tags" bar chart with the same layout as the clip type chart. Click any bar to jump to the clips filtered by that tag.
Below that, a "Stale clips" section shows clips older than 90 days that have never been used. Expand it to see the full list and delete individual clips with a single click.
## Snippets: Multi-Select, Duplication, and Export
Select multiple snippets with Cmd+click or Shift+click. When two or more are selected, a blue action bar appears at the top of the list with a Delete button and a Move to folder dropdown.
A Duplicate button in the snippet detail toolbar creates a copy of the current snippet in the same folder, named "Copy of …".
Two new export buttons in Settings - Export snippets (JSON) and Export snippets (text) - let you take your snippet library out of the app.
## Onboarding
New users now walk through six steps instead of three. The additional steps cover tags and the Tags view, the Snippets tab and placeholder syntax, and a quick tour of search prefixes and the ? shortcut reference.
