Improvements

• Go Runtime Now Works Everywhere - Rebuilt the Go interpreter with self-hosted WebAssembly. No more CDN dependencies that were blocked in some regions. Go code execution is now reliable worldwide.
• Python Runtime Self-Hosted - Core Python runtime (Pyodide 0.29.1) now loads from our servers instead of external CDN. Faster initial load and works in regions where jsdelivr was blocked.

New

• Multi-Language Playground - Playcode now supports Python, SQL, C++, C, and Go alongside JavaScript/TypeScript. All languages run 100% in your browser via WebAssembly. No server, complete privacy.
• Python with Pyodide - Full Python 3.12 with pip package manager. Install NumPy, Pandas, Matplotlib, scikit-learn, and 300+ packages. Visualizations render inline.
• SQL with PostgreSQL - Real PostgreSQL via PGlite with persistent IndexedDB storage. 18+ extensions including pgvector for AI, pg_trgm for fuzzy search. Database Explorer with pagination.
• C++ and C Compilers - Modern C++20 and C17 support via Clang/LLVM compiled to WebAssembly. Write, compile, and run instantly.
• Go Compiler - Run Go code in browser using Yaegi interpreter. Standard library support included.

Improvements

• Language-Aware UI - Header buttons adapt based on project language. Preview for JavaScript, Output for Python/C++/Go, Database Explorer for SQL.
• Python Package Manager - See popular packages (NumPy, Pandas, Matplotlib) immediately. Install any PyPI package by typing its name.
• New Templates - Quick-start templates for Python, SQL (PostgreSQL and SQLite), C++, C, and Go. Create a new project and start coding in seconds.

New

• AI Access Control - Project owners can now disable AI chat for collaborators. Perfect for coding interviews where you want to test candidates without AI assistance. Find the toggle in Share settings (Pro feature).

Improvements

• Redesigned Navigation - Console, Preview, and AI buttons now have text labels for better discoverability. Core features should be visible, not hidden behind icons.

Improvements

• Redesigned AI Mode Selector - The mode selector now explains exactly how to work with AI. Each mode is color-coded: Plan (blue) for planning, Agent (green) for building, and Ask (orange) for questions only.
• Recommended Workflow Guide - The menu now shows "Plan → Agent → Ask" as the recommended workflow, with step numbers (1, 2, 3) and clear descriptions for each mode. Perfect for non-programmers!
• Mode Badges - Each mode has a helpful badge: "Start here" for Plan, "Default" for Agent, and "Read-only" for Ask.
• Learn More Link - Quick access to detailed documentation about how each mode works.

New

• Claude Opus 4.5 is Now Default - As the creator of Playcode, I believe in giving you the best experience from the start. The AI now uses Claude Opus 4.5 by default, the most capable model available. It costs more per message, but the quality difference is immediately visible. Magic should feel like magic.
• Cleaner Chat Interface - Removed the model selector from the chat toolbar for a simpler experience. Power users can still change models via Menu → Preferences → AI Model.

Improvements

• Reduced AI System Prompt - Optimized the AI system prompt by ~60%, making each request slightly cheaper.

Fixes

• Chat Character Escaping - Fixed an issue where HTML entities and escape sequences were displayed in the chat preview instead of actual characters.
• Preview URL Dropdown - The HTML page selector in the preview toolbar now stays open when clicking, allowing you to actually select a page.

Improvements

• AI Import Now Works with Full Responses - Copy the entire AI response including explanations and markdown. We automatically extract the JSON code block and apply changes. No more "Failed to parse" errors!
• Helpful Tooltips - Hover over Copy, Paste, and Apply buttons to see step-by-step instructions on how to use the ChatGPT/Gemini workflow.
• Better Error Messages - When something goes wrong, you now get actionable guidance on how to fix it.

New

• ChatGPT/Gemini Import/Export Buttons - Copy your project files with one click, paste into your AI, then paste the response back and apply changes instantly. Includes Undo/Redo to rollback if something breaks.
• Inspiring Placeholder - The AI input now shows animated examples of what you can build: customer portals, admin dashboards, landing pages, and more.

Improvements

• Consistent Design - All primary action buttons now use the signature orange gradient for a unified look across popups and notifications.
• Pro Badge Styling - Updated Pro badges to match the marketing design with the correct gradient colors.

Improvements

• Truly Empty Templates - Empty JavaScript, TypeScript, HTML, and CSS templates are now minimal. Just the bare essentials with a single comment to get you started from scratch.

Fixes

• Live View Delay - Changing the delay setting now applies immediately. Previously, adjusting the delay in preferences had no effect until page reload.

Changes

• Free tier adjustments - To keep Playcode sustainable and continue offering a great experience, we've had to reintroduce some coding limits for free accounts. Pro users continue to enjoy unlimited lines of code, along with all other premium features. We appreciate your understanding and support!
