Pros & Cons
ECC
- Massive community adoption — over 200,000 GitHub stars and 170+ contributors
- Genuinely solves cross-tool configuration fragmentation for developers using multiple AI coding assistants
- Free tier available for public repo analysis before committing to a paid plan
- Full-depth support is strongest for Claude Code, with other harnesses receiving capability-limited adapters
- Private repo analysis and higher usage limits require the paid Pro tier
- Fast-moving space means ECC and its supported harnesses will likely keep evolving quickly
Sway
- Genuinely no loss of functionality despite the June 2026 desktop app retirement — full web access remains
- Interactive, scrollable format differs from traditional static presentation slides
- Integrated within the broader Microsoft 365 ecosystem
- Windows desktop app was retired June 1, 2026, requiring transition to the web interface
- Experienced a temporary service outage in March 2026, though this appears to have been transient
- Web-only access now for former desktop app users specifically
