+## Sunsetting Cody Free, Pro, and Enterprise Starter plans
+
+### What is the impact?
+
+Starting July 23, 2025, Cody will no longer be available for Free, Pro and Enterprise Starter plans. Existing users will continue to have access until this date.
+
+This change **will not impact Cody Enterprise customers**. They will continue to have access to Cody. We are fully committed and invested in Cody Enterprise and will continue to serve our customers.
+
+### What does this mean if you are a Cody Free, Pro, Enterprise Starter, or Enterprise user?
+
+Starting June 25, you cannot sign up for new Cody Free or Cody Pro accounts, and the new Enterprise Starter workspaces will not include Cody.
+
+If you're a Cody Free user:
+
+- You will have access to Cody Free until July 23, 2025. After this, you'll no longer be able to use Cody.
+- Instead, you can sign up with Amp and receive **$10 in free credits** at [ampcode.com](http://ampcode.com/).
+
+If you're a Cody Pro user:
+
+- You will have access to Cody Pro until July 23, 2025. After this, you'll no longer be able to use Cody.
+- You **will not be charged for Cody Pro** between now and July 23, 2025.
+- Cody Pro customers can sign up with Amp today at [ampcode.com](http://ampcode.com) and receive **$10 in free credits** **plus $30 additional free credits** as a thank you for using Cody Pro.
+
+If you're on Enterprise Starter:
+
+- Your workspaces will have Cody access until *July 23, 2025, after which Cody's access will be removed.
+- Your Enterprise Starter subscription remains fully supported for Code Search, with upcoming improvements like [Deep Search](/code-search/types/deep-search).
+- Enterprise Starter customers can sign up with Amp today at [ampcode.com](http://ampcode.com) and receive **$10 in free credits** **plus $30 additional free credits** as a thank you for using Enterprise Starter.
+
+If you're an Enterprise user:
+
+- **This change will not impact you**. We're fully committed to serving you.
+- You can continue to use Cody Enterprise as this remains fully supported and actively invested in.
+
+### Why is this change being made?
+
+AI is evolving rapidly, and so are developers' workflows. To stay focused and aligned with those needs, we're simplifying our product roadmap and offerings.
+
+**Cody Enterprise will actively be supported, developed, and maintained**. It will continue to offer AI-powered development workflows for secure, collaborative, and large-scale teams.
+
+But with AI now capable of handling more complex, agentic, and autonomous workflows, we've built [**Amp**](https://ampcode.com/) — our agentic, team-ready AI coding tool.
+
+### Is there any replacement for Cody Free and Pro?
+
+Yes, [**Amp**](https://ampcode.com/) is our new AI coding tool for agentic workflows and team collaboration.
+
+It runs in VS Code with compatible forks like Cursor, Windsurf, and VSCodium and as a CLI. It's also multiplayer — you can share threads and collaborate with your team.
+
+Amp is your way forward if you're using Cody Free or Pro. Sign up today for $10 in Amp credits if you're a Cody Free user and $40 in Amp credits if you're a Cody Pro user.
+
+### How can I learn more about Amp?
+
+We've built [Amp's Manual](https://ampcode.com/manual) to help you get started with Amp. In addition, if you need more help for this Cody > Amp transition please reach out to us in [Discord](https://discord.com/servers/sourcegraph-969688426372825169).
