Use tool ↗About delta.dev
Delta is a collaborative workspace for coding with agents, built by Zed Industries, the team behind the Zed editor. You describe a task in a thread, an agent works in an isolated checkout of your repository, and you review the result with the conversation, reasoning and every edit kept next to the code, so a change can be traced back to why it was made or reverted to any step. Teammates and agents can work in the same thread, and comments on a specific passage feed the next revision. It is in beta, with desktop builds for macOS, Linux and Windows plus a web version, and it shares accounts, plans and credits with Zed.

Pros & cons of delta.dev
Delta comes from the team behind the Zed editor and targets the real bottleneck of agent-assisted work: reviewing what an agent changed together with the conversation that produced it. It has moved past the waitlist into a downloadable beta for macOS, Linux, Windows and the web, free with your own keys and $10 a month for hosted models. It is still early-access software, so expect the workflow and limits to keep changing.
Pros
- Built by the team behind the Zed editor, with the same account and plans
- Keeps the reasoning and every edit of a thread attached to the code, with revert to any step
- Free Personal plan works with your own API keys or external agents
- Desktop builds for macOS, Linux and Windows plus a web version
Cons
- Still beta, downloaded under an Early Access Agreement
- Pro includes only $5 of hosted-model tokens a month before usage billing starts
- Zed's edit predictions are not available inside Delta
Best for
- Teams already using Zed who review a lot of agent-written code
- Developers who want each change tied to the prompt and reasoning behind it
- People who already pay for model API keys and want a free agent workspace on top
Not for
- Teams that need a generally available tool with support commitments today
- Developers on Intel Macs, since the macOS download is Apple Silicon only
Watch out: The $10 Pro headline covers just $5 of hosted-model tokens; long agent sessions are billed by usage on top, so set a spending limit in your Zed account.
