+
+# Open WebUI
+
+Open WebUI is a user-friendly web interface for interacting with Large Language Models. It provides a ChatGPT-like interface that can connect to various LLM providers including OpenAI, Ollama, and more.
+
+This module installs and runs Open WebUI using Python and pip within your Coder workspace.
+
+## Prerequisites
+
+- **Python 3.11 or higher** must be installed in your image (with `venv` module)
+- Port 7800 (default) or your custom port must be available
+
+For Ubuntu/Debian, you can install Python 3.11 from [deadsnakes PPA](https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa):
+
+```shell
+sudo add-apt-repository -y ppa:deadsnakes/ppa
+sudo apt-get update
+sudo apt-get install -y python3.11 python3.11-venv
+```
+
+## Basic Usage
+
+```tf
+module "open-webui" {
+  count    = data.coder_workspace.me.start_count
+  source   = "registry.coder.com/coder-labs/open-webui/coder"
+  version  = "0.9.0"
+  agent_id = coder_agent.main.id

+icon: ../../../../.icons/antigravity.svg
+verified: true
+tags: [ide, antigravity, ai, google]
+---
+
+# Antigravity IDE
+
+Add a button to open any workspace with a single click in [Antigravity IDE](https://antigravity.google).
+
+Uses the [Coder Remote VS Code Extension](https://github.com/coder/vscode-coder).
+
+```tf
+module "antigravity" {
+  count    = data.coder_workspace.me.start_count
+  source   = "registry.coder.com/coder/antigravity/coder"
+  version  = "1.0.0"
+  agent_id = coder_agent.example.id
+}
+```
+
+## Examples
+
+### Open in a specific directory
+
+```tf
+module "antigravity" {
+  count    = data.coder_workspace.me.start_count
+  source   = "registry.coder.com/coder/antigravity/coder"
+  version  = "1.0.0"
+  agent_id = coder_agent.example.id
+  folder   = "/home/coder/project"
+}
+```
+
+### Configure MCP servers for Antigravity
+
+Provide a JSON-encoded string via the `mcp` input. When set, the module writes the value to `~/.gemini/antigravity/mcp_config.json` using a `coder_script` on workspace start.
+
+The following example configures Antigravity to use the GitHub MCP server with authentication facilitated by the [`coder_external_auth`](https://coder.com/docs/admin/external-auth#configure-a-github-oauth-app) resource.
+
+```tf
+module "antigravity" {
+  count    = data.coder_workspace.me.start_count
+  source   = "registry.coder.com/coder/antigravity/coder"
+  version  = "1.0.0"
+  agent_id = coder_agent.example.id
+  folder   = "/home/coder/project"
+  mcp = jsonencode({
+    mcpServers = {
+      "github" : {
+        "url" : "https://api.githubcopilot.com/mcp/",
+        "headers" : {
