Decode JWTs & Format JSON

Click any raw JWT or minified JSON to instantly decode and format it on-device. No more pasting into random browser tabs.

OCR for Stack Traces

Someone sent a screenshot of an error? Copy it. L2Cache extracts the text instantly using Apple's Vision framework.

Terminal History

L2Cache detects terminal output and automatically extracts the root command (like docker, git, or npm) to tag your clips, making it easy to filter, find, and replay your past commands.

IA Agent Session History

Every Claude Code and Codex CLI session is captured in your clipboard history — prompts, responses, token usage, and cache hit rates. Review, search, and replay your IA coding sessions without leaving your workflow.

IA Data Generation

Select a SQL schema or Swift struct and run an IA prompt directly inside the clipboard to generate mock data instantly.

L2Cache lets you create custom actions in Bash or Ruby. Target actions dynamically based on content types like SQL, Docker, YAML, or GraphQL. Format, fetch, or filter copied text entirely on-device.

From Raw Data to Usable Code

Ordinary clipboards merely store raw data like unprocessed ore. L2Cache works as a miner, instantly refining that material into polished, ready‑to‑use gold.

Wall of Love

Developers love L2Cache

Don't just take our word for it. Here is what engineers are saying.

★★★★★

"This is hands down the best clipboard manager for engineers. The ability to pipe my clipboard directly into a Ruby script without leaving my IDE is mind-blowing. It replaced Maccy for me."

S

Sarah J.

Senior Backend Engineer

★★★★★

"The Smart Actions are a game changer. Being able to extract a JWT payload or pretty-print JSON with a single shortcut saves me so much context switching every day."

M

Michael T.

Fullstack Developer

★★★★★

"Finally, a native macOS app that respects developers. It's incredibly fast, the SQLite search is instant, and the UI is absolutely gorgeous. Worth every penny."

D

David R.

iOS Engineer

FAQ

Common Questions

How much does L2Cache cost? +
L2Cache is a $4.99 one-time purchase with lifetime access. Pay once, own forever — all future updates are included with no recurring subscriptions.
Does L2Cache keep my clipboard history private? +
Yes. L2Cache stores your clipboard history locally on your Mac and its IA runs entirely on-device using Apple Intelligence. No clipboard content is ever sent to any server.
What Macs does L2Cache work on? +
L2Cache runs on macOS 13 Ventura or later. Core clipboard history and search work on any supported Mac; the on-device IA features (smart titles, Transformation intelligente) require macOS 15.1+ on Apple Silicon.
How is L2Cache different from the built-in macOS clipboard? +
macOS only keeps the last copied item. L2Cache keeps unlimited history with full-text search, OCR search inside screenshots, smart albums, regex grep, JWT/JSON decoding, SQL data generation, custom scripts — and works back to macOS 13.
