Clipboard history for copied technical data
Capture JSON, curl commands, JWTs, SQL, config, and snippets—without losing them, reformatting them by hand, or exposing secrets.
Local-first. Secret-safe. Built for macOS developers.
Developers don't copy plain text
Understand what you copied
You copy API payloads, tokens, curl commands, SQL queries, env values, and snippets all day. Generic clipboard tools store them. StackClip makes copied technical data usable.
Smart classification
StackClip detects 36 content types automatically—JSON, JWT, curl, SQL, YAML, env, and more. Find what you copied without digging or guessing.
Contextual actions
Format JSON, decode JWTs, minify, transform—right where you copied it. The right action appears automatically.
Developer utilities
Case conversion, CSV↔JSON, hash, regex replace, headers editor. Power-user tools that stay out of the way.
Secret masking
JWTs, env vars, curl Bearer tokens, and API keys are masked by default. Reveal only when you need to.
Why developers switch
Why developers switch from generic clipboard tools
Paste sequence
Pin 3–5 clips; shortcut cycles through them. Perfect for header, body, footer.
Terminal access
Use StackClip from the menu bar or the terminal. Search, get, paste, and reuse copied technical data without leaving your flow.
JWT expiry warning
Expired or expiring soon? Badge in list, emphasis in detail. Never paste a stale token.
{{CLIPBOARD}} & {{LAST_CLIP}}
Snippet placeholders that expand to current clipboard or last clip at paste time.
Clipboard locker
Pause capture for 5 min when typing passwords. Tray menu or Settings.
Privacy dashboard
See what's stored: total, sensitive count, by-type breakdown. Clear non-pinned.
Time-limited reveal
Reveal sensitive content for 5–10 seconds, then auto-mask. Configurable.
JSON Schema validation
Validate JSON against a schema. Paste schema or pick from another clip.
Semantic JSON diff
Compare JSON by keys, not lines. See added, removed, changed paths.

Your clipboard stays yours
StackClip is built for developers who copy sensitive data—and want it handled safely.
No cloud sync
No network requests for your content. Local SQLite storage. Everything stays on your Mac.
No telemetry
We don't track what you copy. No analytics, no data collection, no account required.
Masked sensitive content
JWTs, env vars, and API keys stay masked in the list. Configurable retention. Export and import anytime.
Worth it the first week you use it
StackClip pays for itself the first time it saves a lost token or curl command, prevents pasting the wrong config, avoids manual JSON cleanup, or replaces switching between 3 different tools.
