Before getting into product updates, here's some cheer with *Snow Mode*. Try it out today! ## Platform updates ### Snow Mode Snow Mode animation showing falling snow effect in the Replit IDE ### Custom prompts **Update (December 2025):** Assistant has been deprecated. For quick, targeted edits, use [Lite mode in Agent](/core-concepts/agent/agent-modes). Custom prompts allow you to take full control of how Assistant interacts. From setting up specific coding standards to customizing Assistant defaults, Custom Prompts have you covered. You might add things like: * A specific coding style or framework * Specific problem solving techniques * Package management preferences For example, you might add: ``` use pnpm for package management use motion/react instead of framer-motion always use claude-3-5-sonnet-20241022 as your model ``` Screenshot of Custom Prompts interface showing prompt configuration options To spice things up, you can even add some personality to Assistant (this is how I understand the younger generation) Screenshot showing Gen Z style conversation with Assistant ### Package installs Assistant can now install your packages for you in a single click. Animation demonstrating one-click package installation feature ### Replit App theming Your projects just got a major glow-up. No code required 💅 Now, you can ask Agent to build a React Replit App and customize it effortlessly with no-code theming tools: * Change the primary color * Switch between light and dark modes * Personalize your app's aesthetics to be truly yours Animation demonstrating the Replit App theming feature Copy paste this prompt to Agent to try it out! ``` Build me a todo list app in React ``` ### Database notifications You now get a notification when Agent adds a database to your Replit App. Keep an eye out for it in the bottom left.

It works like an infinite idea generator that helps guide you from idea to publish-ready software, fast. Animation showing feature recommendations and suggestions ### Integration visibility Agent now features enhanced integration visibility, allowing you to better track and manage integrations throughout your workflow. Supported integrations include OpenAI, Stripe, Firebase, and more! Animation showing integration visibility features and options ### Workflows A Workflow is an easily configurable "Run" button that can run any command(s) you'd like. It is a reusable, customizable sequence of steps that can be executed within your Replit App. They can be as simple as running **`python main.py`** or as complex as executing a multi-step procedure. Example Use Cases: * Run multiple services in parallel (e.g., frontend + backend) * Execute files or commands sequentially (e.g., run linter → run tests, compile → execute code) To start [creating workflows](https:/.replit.com/replit-workspace/workflows#creating-workflows), go to the Workflows pane by using the tools sidebar menu, or search for the Workflows pane using **`Command + K`**.
