Why ocsight?

✅ Accurate

Real costs from actual model pricing, no estimates

🚀 Fast

Built with Bun for maximum performance:

• Zstd compression (faster/smaller than gzip)
• SIMD-accelerated ANSI processing
• Native TypeScript execution
• Concurrent test execution
• Handles 10k+ sessions instantly with optimized caching

💰 Smart Budgets

Set limits, get alerts, forecast spending with conservative projections

🔴 Live Monitoring

Watch costs accumulate in real-time

📊 Comprehensive Analytics

Detailed breakdowns by provider, model, and time period

🔒 Private

Runs locally, never sends your data anywhere

Requirements

• Bun runtime (recommended) or Node.js 18+
• OpenCode installed
• Session data in ~/.local/share/opencode/storage/

Performance with Bun

ocsight is optimized for Bun v1.3+:

• 6-57x faster ANSI processing with native SIMD operations
• Smaller cache files using zstd compression instead of gzip
• Faster startup with native TypeScript execution
• 166ms build time using Bun.build API
• Concurrent testing for faster test execution

When running with Bun, you automatically get:

• Native zstd compression for cache (faster + smaller than gzip)
• SIMD-accelerated ANSI stripping in live monitoring
• OS-native credential storage for secrets
• Faster JSON parsing and file I/O

Node.js fallbacks ensure full compatibility without Bun-specific features.

Data Sources

ocsight reads from your local OpenCode storage:

~/.local/share/opencode/storage/
├── session/<project-hash>/ses_*.json   # Session metadata
└── message/<session-id>/msg_*.json     # Individual messages

Development

git clone https://github.com/heyhuynhgiabuu/ocsight
cd ocsight
bun install
bun run build
bun test
bun run packages/cli/src/index.ts summary

Build Process

ocsight uses Bun's native build system:

# Bundle CLI with Bun.build API
bun run scripts/bundle-cli.ts

# Compile standalone executables
bun build packages/cli/src/index.ts --compile --outfile ocsight-linux-x64

# Run tests with concurrent execution
bun test --concurrent

# Watch mode for development
bun test --watch

Cross-Platform Builds

Native executables are built via CI:

• Linux x64 - Ubuntu 22.04 build
• macOS x64 - Intel Mac build with code signing
• macOS ARM64 - Apple Silicon build with code signing
• Windows x64 - Windows build with .exe output

Download from releases page.

Configuration

ocsight works out of the box. Optional config:

ocsight budget set --monthly 200    # Set budget
ocsight config show                  # View config
ocsight config doctor               # Validate setup

Troubleshooting

No data showing?

• Check OpenCode is installed: which opencode
• Verify data exists: ls ~/.local/share/opencode/storage/
• Run doctor: ocsight config doctor

Wrong costs?

• ocsight uses models.dev pricing
• Some providers (github) show $0.00 for free tiers
• Custom/enterprise pricing not supported

Performance issues?

• First run caches data (may be slow)
• Use --days flag to limit data range
• Large histories (>10k sessions) may be slow
• Tip: Run with Bun for 6-57x faster performance vs Node.js
