How to Choose a Coding Agents Tool
Key criteria to evaluate when comparing Coding Agents solutions:
About Open Code
OpenCode is an open-source AI coding agent built by Anomaly that runs primarily in the terminal but is also available as an IDE extension and a beta desktop app on macOS, Windows, and Linux. Its standout feature is privacy-first design: OpenCode does not store any of your code, prompts, or context data, making it suitable for regulated environments and air-gapped workflows.
The agent supports 75+ LLM providers through the Models.dev catalog including Claude, OpenAI GPT, Google Gemini, GitHub Copilot, ChatGPT Plus/Pro accounts, and local models. It includes LSP integration for accurate code understanding, multi-session capability for running parallel agents on the same project, and shareable session links for debugging and team review.
OpenCode is fully free and open-source under MIT, with an optional paid "Zen" service for optimized models. Source is at github.com/anomalyco/opencode (147K+ stars, 6.5M monthly developers as of April 2026). It hit #1 on Hacker News on March 20, 2026, and crossed Cline + OpenHands in star velocity earlier in the year.
About Replit Agent
Replit Agent is an AI-powered development tool using effort-based pricing that scales with request complexity. Simple changes cost under USD 0.25, with payment based on actual work performed. Replit Core (USD 20-25/mo) includes USD 25 in monthly credits, while Pro (USD 100/mo) offers tiered credits from USD 100-4,000/mo with volume discounts and credit rollover. Economy Mode costs roughly one-third of Agent 3, while Turbo Mode (Pro/Enterprise only) is 2× faster but costs up to 6× more. Pro unlocks access to powerful Agent modes, priority support, up to 15 builders, and credit rollover. Platform combines IDE, hosting, and AI agent capabilities for comprehensive development environment.
