5 Free & Open-Source Alternatives to UTM.io

Looking for a free or open-source alternative to UTM.io? UTMcraft is the closest direct swap — MIT-licensed source on GitHub, or a $19 one-time packaged install. Since you're already auditing what you pay UTM.io every month, here are four more pay-once tools from the same catalog worth a look while you're at it — different jobs, same idea: buy the software once instead of renting it forever.

1. UTMcraft — replaces UTM.io

Self-hosted UTM builder with naming enforcement, bulk CSV generation and click-tracking dashboards. $19 once vs UTM.io's $29/mo. Free on GitHub, or the packaged installer on Whop.

Why this list is worth bookmarking

Every app above is a one-time purchase with MIT-licensed source, no accounts with us and no telemetry. None of them are trying to be the next UTM.io — they're trying to be the last subscription you pay for that specific job.
