Pros & Cons
Chatty
Pros
Completely free with no subscription, ads, or paid tiers
Genuinely cross-platform via Java, running on Windows, macOS, and Linux
Unique in-client tools for streamers to update title, game, and tags without a browser
Long-running, mature project with community translations into several languages
Portable version removes the need to separately install a Java runtime
Cons
Java-based architecture and IRC-style interface can feel dated compared to newer, more modern-looking clients
Less actively marketed and may be less well known than alternatives like Chatterino
Requires a Java runtime unless using the bundled portable package, adding setup friction for some users
Third-party emote service support and customization depth may lag behind newer competing clients
As a community-maintained tool, update cadence depends on volunteer developer availability
Spark Mail

Useful built-in AI writing and meeting-notes tools
Strong team collaboration features for shared inboxes
Available across all major desktop and mobile platforms
Full AI features require the paid Plus or Pro plan
AI usage is credit-limited even on paid tiers
Some advanced workflow features are not yet fully available
Per-user pricing can add up for larger teams
