Pros & Cons
DAViCal
Pros
Completely free and open source under the GPLv2 license
Full control and ownership over calendar and contact data via self-hosting
Implements open CalDAV/CardDAV standards, ensuring broad client compatibility
Mature, long-standing project with a stable feature set for group calendaring
Cons
Requires manual setup and maintenance of a PHP and PostgreSQL server stack
Administrative interface is functional but visually dated compared to newer alternatives
No official commercial support channel; relies on community and third-party providers
Less actively developed than some newer self-hosted alternatives like Baikal or Nextcloud
tradesviz
Pros
Very deep analytics: 600+ stats/charts plus a customizable, drag-and-drop dashboard builder
Broad asset-class and broker coverage, with auto-sync from 30+ brokers and manual import from 200+ platforms
AI features (AI Trade Chat, AI Coach) go beyond raw logging to help surface behavioral trading mistakes
Built-in trading simulator and technical backtester let users test strategies without risking capital
Cons
Pricing is listed in EUR, which may be a minor friction point for traders expecting a USD-first checkout
Advanced features like the real-time screener, universal simulator, and options flow are gated behind the top Platinum tier
Free tier is capped at 3,000 executions/month and stock assets only, so active multi-asset traders will likely need to upgrade quickly
