Platform Philosophy & Approach
GitHub Copilot
GitHub Copilot has evolved into a multi-model agentic platform that integrates across 10+ IDEs with models from OpenAI, Anthropic, Google, and xAI. Its coding agent autonomously resolves GitHub issues, and MCP support is GA across all IDEs.
- • Multi-model picker: GPT-5, Claude Opus 4.5, Gemini 3
- • Coding agent resolves issues via GitHub Actions
- • MCP, plan mode, and custom agents now GA
- • Agent mode for autonomous multi-file editing
Replit
Replit has pivoted to target non-technical users and "citizen developers" — 58% of its business builders are not engineers. Agent 3 offers 200-minute autonomous sessions, self-testing, and Design Mode for building high-fidelity apps in minutes.
- • Agent 3: 200-min autonomy, self-testing, sub-agent spawning
- • Design Mode and Fast Build for rapid app creation
- • iOS & React Native app building from prompts
- • 35M+ users, $3B valuation, Google Cloud partnership
AI Agent Capabilities
GitHub Copilot Agent
Agent Mode (GA)
Generally available since Sep 2025 — autonomous multi-file editing with plan mode, MCP tool integration, and custom agents across all supported IDEs.
Coding Agent
Assign GitHub issues directly to Copilot. It spins up a GitHub Actions environment, writes code, opens draft PRs, and pushes to dedicated copilot/ branches.
MCP & Extensibility
Model Context Protocol support is GA across all IDEs. AGENTS.md files define project-specific agent behavior. Task assignment via Slack, Teams, and Linear.
Replit Agent
Agent 3 (200-Min Autonomy)
Operates autonomously for up to 200 minutes (10x Agent 2). Self-tests apps in browser, generates bug reports, and fixes issues — 3x faster than Computer Use models.
Agent Spawning & Queue
Creates specialized sub-agents from natural language for Slack, email, Telegram, and Notion integrations. Agent Queue organizes requests like a task list.
Mobile App Building
Build iOS and React Native apps from prompts. Preview via QR code or Expo Go, with one-click App Store publishing. Design Mode creates interactive designs in under 2 minutes.
