Pricing questions
Credits, exports and payment. Everything else is answered on the full FAQ.
How much does TopoLines cost?
Generating and downloading a standard PNG is free — just sign in with Google or GitHub. Pro features are pay-as-you-go through credit packs: €5 for 20 credits, €10 for 100, €35 for 500. There is no subscription and no monthly fee.
How many credits does one export cost?
Around two credits for a typical export. The exact cost scales with the area you drew and the resolution you asked for, so a small zone at 10 m terrain costs less than a 2000 km² one. The price is shown before you confirm.
Do credits expire?
Never. A pack is a one-off purchase and the credits stay on your account until you spend them — there is nothing to cancel and nothing that lapses.
Is there a subscription or a free trial?
Neither, because neither is needed. The free tier is permanent rather than a trial, and Pro is bought in credit packs rather than billed monthly.
What payment methods do you accept?
Card and PayPal, handled by Lemonsqueezy, which acts as merchant of record and takes care of VAT and invoicing.
I paid but my credits aren't showing?
That normally means you checked out with a different email than the one you log in with. Open the claim page and enter your order ID and checkout email — both are in your Lemonsqueezy receipt — to move the credits onto your account.
