Been experimenting with using Lightning Network for micropayment-powered developer tools. Here is what I have learned running this in production.
The Setup: SatsPaste (http://5.78.129.127/paste/) — a pastebin that charges 100 sats per paste instead of tracking users or showing ads. Free tier available for small pastes.
Why Lightning works for this:
- Payment is instant (< 100ms)
- No accounts needed — scan QR, pay, done
- 100 sats is psychologically easy (< $0.10)
- No chargebacks, no payment processor fees
- Works globally without KYC
Technical details:
- Using Coinos.io API for invoice creation and payment verification
- Total payment code is about 50 lines of JavaScript
- Running on a $5/month VPS alongside 15 other tools
The bigger vision: Lightning makes it possible to build a new category of tools — no-account, no-tracking, pay-per-use. We are also running:
- A free Nostr DVM (Data Vending Machine) with 6 services processing 2000+ requests/day
- A paid Nostr relay (500 sats lifetime access)
- 15+ free web tools at http://5.78.129.127/
The economics work even at tiny scale. A few hundred users paying 100 sats each covers hosting costs.
Anyone else building Lightning-powered tools? Would love to hear about your experience.
Btw your TLS cert is for https://5.78.129.127.nip.io/paste/ but you can get certificates for raw IP addresses as well (if you want that)
Do pastes expire? Otherwise no charge on access results in an increasing catalogue you’ll have to pay for.
Also what are the current TX costs to enter the lightning Network? How is this done typically? What software on Linux would you recommend? Is there something similar for Ethereum?
