Search clipboard history, shell commands, OCR screenshots, Claude Code and Codex sessions—100% locally. Format JSON, decode JWTs, and scrub sensitive secrets with private on-device intelligence.
Find the command, coding session, or copied snippet you remember without losing the clipboard tools developers already use L2Cache for.
L2Cache doesn't just store strings. It understands code, extracts errors, and connects context. Scroll through to see each tool in action.
Ordinary clipboards merely store raw data like unprocessed ore. L2Cache works as a miner, instantly refining that material into polished, ready‑to‑use gold.

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."
"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."
"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."
