Keygen is a well-regarded, developer-first licensing and distribution API. It is fair-source (the API is available to self-host), supports node-locked, floating, offline, and subscription models, and offers SDKs across many languages. If you need a mature, self-hostable platform with a large enterprise ceiling, Keygen is a strong choice.
But it is not the only option, and it is not always the right fit. Keygen's free Dev tier is capped (around 100 active licensed users with hard limits), and commercial projects move onto paid tiers as they grow. If you are an indie developer or a small software vendor who wants to start free, ship in minutes, and avoid counting active users, a simpler hosted option may suit you better.
What to look for in a licensing tool
The fundamentals are the same across good tools. Insist on all of these:
- Signed validation. The server must sign each response with a private key so a cracked "fake server" cannot forge a valid reply. This is the core of real anti-piracy.
- Device binding (node-locked). Tie keys to a limited number of machines.
- Floating licenses. Cap concurrent usage for teams.
- Offline activation. Verify a signed license file with no network for air-gapped machines.
- A real SDK plus a plain REST API so you can integrate from any language.
Keygen offers all of these. So does Licers. The differences are pricing, simplicity, and how quickly you can ship.
Licers as a Keygen alternative
Licers is a hosted licensing platform focused on being free and simple to start:
- Free and unlimited right now — products, keys, devices, validations, offline files, floating licenses, and webhooks, with no active-user counting.
- Ed25519 signed validation — every response is verified against a public key you embed; a forged reply is cryptographically impossible.
- Python-first SDK (
pip install pylicensify) plus a plain REST API for any language. - Runs on a global edge, so there is no server for you to operate.
Where Keygen leads: a self-hostable open API and a large, proven enterprise tier. If self-hosting or enterprise scale is a hard requirement, prefer Keygen. If "free, hosted, and shipping today" matters more, try Licers.
Which should you choose?
- Choose Keygen if you need self-hosting, are comfortable on paid tiers, or expect enterprise-scale volume.
- Choose Licers if you are an indie developer or small vendor who wants signed validation, device binding, floating and offline licensing for free, with a five-minute Python setup.
Frequently asked questions
Is Licers really free?
Yes. Every feature is currently free and unlimited, with no active-user cap. No credit card is required to start.
Does Licers support the same licensing models as Keygen?
It covers the common ones: node-locked (device binding), floating (concurrent seats), and offline license files, all with signed validation.
Can I move off Licers later?
Yes. Licensing is a thin integration — a validate call plus a public key — so you are never deeply locked in.
