As answered by people managing Tracklyst.app and Opalstack.
Tracklyst.app's answer
Every competitor in this space requires you to upload your files to their servers. Tracklyst doesn't. That means no storage tiers, no upload wait times, no duplicate files to manage, and no version confusion. You update a mix in Dropbox and your client automatically hears the new version — no new link needed. Combined with waveform feedback, version stacking, a listener portal, and Dolby Atmos support, Tracklyst gives professional audio engineers everything they need without the overhead.
Tracklyst.app's answer
Mixing engineers, mastering engineers, music producers, and labels who share audio with clients for review and approval before release. Anyone who has dealt with expired WeTransfer links, feedback buried in email threads, or re-uploading the same file to three different platforms every time a mix changes.
Tracklyst.app's answer
Tracklyst started as a tool we needed ourselves with features that were lacking in other sharing platforms. Designed and built by two audio engineers with decades of experience engineering, mixing, mastering music and helping others make sense out of chaos. Yes, there are apps that let you share audio, share feedback, but we've added more features we found helpful.

Vanilla JavaScript SPA, Netlify (hosting and serverless functions), Netlify Blobs, Supabase, Resend, Dropbox API, OneDrive API, Cloudflare DNS, Stripe, WaveSurfer.js.
Tracklyst.app's answer
Tracklyst is the only audio sharing platform that streams directly from your existing Dropbox or OneDrive. Nothing is re-uploaded, re-hosted, or compressed. Your files stay exactly where they already live — and because we connect to the live source, your share link is always current without sending a new one every time a mix changes.
