Where they actually differ
Not feature checkboxes — the choices that change how each one behaves.
How the bill is built
Retell AI
Itemised. Infrastructure plus speech plus model, chosen per agent — transparent, and it moves when you change any component.
Voxera
One allowance. Changing model or voice does not change what the month costs.
The cheapest realistic minute
Retell AI
Their own stated floor is $0.07 with the least expensive components selected.
Voxera
About $0.030 on Scale and $0.038 on Hobby, including providers.
Where an agent lives
Retell AI
Configured in their dashboard, reached over telephony or their web widget.
Voxera
Published as an immutable version your own app connects to through an SDK.
Choose Retell AI if
You need phone calls, high concurrency on a small plan, or the specific add-ons they sell — denoising, PII removal, guardrails.
Choose Voxera if
Your voice agent belongs inside your own product rather than on a phone line, and you would rather forecast one number than six.
