Why people leave Transistor
Transistor is sold as a subscription — $19/mo, which works out to roughly $228 per year and $1,140 over five years. The product keeps working the same whether you pay or not, but access stops the moment you cancel: the fee is for permission, not for ongoing work done on your behalf. The tools above do the job on your own hardware or your own server, so the cost is fixed at the sticker price.
Common questions
Is there a one-time-purchase alternative to Transistor?
Yes — Castport ($99 once). Each replaces the core job Transistor charges a subscription for, and none of them has a renewal.
How much does Transistor actually cost over time?
Transistor is listed at $19/mo — roughly $228 per year, or $1,140 over five years. The alternatives on this page are single payments, so their cost never grows.
What happens to my data if I leave Transistor?
The pay-once tools on this page run on your own machine or your own server, so your files and records live with you instead of inside a rented account. Check each product page for import and export details before you switch.
