Delta

About

Delta keeps your conversations and code in one place. It anchors every change, so your reasoning lives on with the results.

You can work in the Delta app or from your terminal with the Delta CLI (beta). Threads let you work with your team and your agents side by side, and a shared session lets a teammate join from their own. A thread shared from Claude Code can be joined from the Delta app, and the reverse also works.

Underneath both is DeltaDB, a version control system that records every edit with the conversation behind it. You can swap the model, the harness, or the machine, and every change and its conversation stay in DeltaDB. You can also invite teammates into the same thread to review.
