Alternatives

Honest roundups of what else you can use, grouped by the reason you are leaving rather than by vendor. Each page names the real options with what they cost and links the vendor's own pricing so you can check it. Mirrors appears once on each list, under the one reason where it is genuinely the answer, and every page says when to stay where you are.

Last updated 2 August 2026. Every price on these pages was checked against the vendor's own site, none of them earlier than 2 August 2026.
