Does Leaxor have a subscription or a free tier?

There's no free tier, and you never need a subscription.

Pay as you go: credits cost $0.10 each with a 50-credit ($5) minimum purchase, they never expire, and you pay only when you generate something. Nothing renews and nothing resets, so a quiet month costs nothing.

Being straight about the trade: a free tier would let you try before paying, and Leaxor doesn't offer one. The entry point is a $5 top-up with no recurring commitment, enough for one to three finished videos depending on tier.
