Crush vs OpenCode 2026: Terminal AI Coders Compared

TL;DR Verdict Who Each CLI For

OpenCode dominates with 188k GitHub stars vs Crush's 27k. Both free and open-source. OpenCode wins for most users: bigger community, broader model support, mature features. Crush edges out in terminal UI polish via Charm Bubbletea framework. Choose OpenCode for general AI coding. Pick Crush if you love Charm ecosystem or want prettiest terminal experience.

Shared Open-Source Heritage Divergence

Both born from open-source terminal movement. Crush comes from Charm team (makers of Bubbletea, lipgloss, Bubbles) – heavy Go TUI DNA. OpenCode from SST team behind Serverless Stack – focuses full-stack devs. Both open-source, both terminal-native. Crush uses own Bubbletea for rendering. OpenCode builds directly on terminal APIs.

Crush emphasizes glamour – colors, animations, smooth interactions. OpenCode prioritizes speed and simplicity – minimal visual weight, pure utility. Different philosophies: Crush makes terminal feel modern app. OpenCode stays lean like traditional CLI.

Model Support & BYO-Key Economics

Both bring-your-own-key. No built-in model billing. Connect any provider via API key. Crush supports multiple providers out of box. OpenCode provider-agnostic too. Cost depends entirely on which frontier model you choose – no surprises from tool markup.

Both allow custom model endpoints. Swap between cheap fast models and expensive powerful ones per task. BYO-key means zero vendor lock. You own relationship with model provider. Both tools charge nothing beyond what you pay model API.

TUI Polish, LSP & MCP Integration

Crush ships stunning TUI out of box. Bubbletea gives smooth animations, responsive layouts, true color support. Tab completion inline, diffs render with syntax highlights. Charm trademark: every pixel polished.

OpenCode TUI functional but spartan. Focus on speed – less decoration, more throughput. Still supports split panes, real-time streaming. Both provide language server protocol (LSP) integration for code intelligence – type hints, go-to-definition, diagnostics.

MCP (Model Context Protocol) support tiered. OpenCode offers deep MCP plugin system – extend with custom tools, context providers, action handlers. Crush supports MCP too but more limited. OpenCode ecosystem bigger for MCP extensions.

Momentum Signals – Live GitHub Stars

• Crush: 26,705 stars
• OpenCode: 188,313 stars

OpenCode 7x more stars. Community engagement, contributions, issues – all scale with stars. OpenCode moves faster, more third-party resources, better long-term survival odds. Crush smaller but loyal following in Charm niche.

Recommendation – Which Terminal Agent Adopt

For most developers: OpenCode. Larger community, more models, richer MCP ecosystem, lower risk. Stars don't lie – 188k users trust it.

Choose Crush if: you live in Charm tools (Wish, Soft, Bubbles), need jaw-dropping terminal UI, or prefer Go TUI stack. Crush delivers luxury terminal experience.

Both solid. OpenCode the safer bet for general AI coding. Crush the aesthetic option for terminal purists.
