Zwiftalizer is Now TrainerDX

Hello everyone!

Mike Hanney here. Zwiftalizer is officially rebranding to TrainerDX and moving to trainerdx.com. All your existing data and accounts are safe, just update your bookmarks!

Why the rebrand?

The site has evolved from a free analysis tool to a freemium service:

  • Free Tier - Everyone gets 5 free tokens a month
  • Standard Analysis (1 token) - The log analysis you already know: graphics performance, network stability, sensor connectivity, hardware profiling.
  • Advanced Analysis (1 token) - New! Intelligent rule engine with 50+ automated checks, personalized optimization recommendations, and correlation analysis to identify the why behind performance issues

Additional tokens can be purchased at any time. No subscriptions, no ads, and no data selling. Just transparent pricing and pay for what you need.

The Commercial Side

Zwiftalizer started as a passion project in 2016, but as the user base grew, hosting costs for running analysis became unsustainable. The freemium model ensures TrainerDX remains available long-term while keeping essential analysis free for everyone.

Since TrainerDX is now a commercial offering with paid features, I’m being intentional about branding. The old name “Zwiftalizer” may imply official Zwift affiliation, which could create brand confusion. TrainerDX clearly signals this is an independent tool built for the Zwift community, not by Zwift.

Your data, your privacy, your performance insights - all still yours. Same analysis, now with advanced tools to help you optimize your setup. I take information security and confidentiality extremely seriously and will never sell or share your data.

What’s Next?

  • Bookmark trainerdx.com
  • Log in with your existing account (no need to sign up again)
  • Try the Advanced Analysis with your 5 free tokens a month.

Note: If you’re still seeing the old site, or run into any issues, try a hard refresh to clear your browser cache:

  • Windows: Ctrl + Shift + R
  • Mac: Cmd + Shift + R

Thanks for your ongoing support and patience while the domain switches over - should be available for everyone by midnight UTC 26th October 2025.
