 Spilltea supports plugins written in **Lua**. Plugins are loaded from `~/.config/spilltea/plugins/` by default and do not require recompilation or access to the source code.
 For a full reference and examples, see the [plugin documentation](./docs/plugins.md) or [plugin examples](./plugins/).
 
+## Vim / Neovim Integration
+
+Spilltea pairs naturally with Neovim. If you live in your editor, these plugins let you inspect and transform captured traffic without switching context:
+
+- **[sttr.nvim](https://github.com/anotherhadi/sttr.nvim)**: Run string transformations (base64, URL encode/decode, hex, hashing, and more) on any selected text directly from Neovim. Handy for decoding values spotted in the proxy history.
+- **[jwt-tui.nvim](https://github.com/anotherhadi/jwt-tui.nvim)**: Decode and inspect JWT tokens in a floating TUI window. Great for quickly reading tokens intercepted through the proxy.
+
+Both plugins are built to feel native in a terminal workflow, just like Spilltea.
+
 ## Deployment
 
 spilltea runs **locally** on the machine used for pentesting or CTF. There is no separate server component.
