Testing lightning applications and protocol changes in realistic conditions is challenging. While many solutions exist for creating regtest and signet networks, producing regular payments within these networks requires custom scripting and constant attention.
SimLN fixes this by letting you simulate payment activity on any test network!
- Random activity generated based on network topology.
- User-specified activity execution for specific payment flows.
- Cross implementation lightning support.
For Lightning spec devs
Easily test protocol changes against realistic network conditions.
For app devs
Stress test your lightning enabled application to see how it performs in real-world, liquidity constrained environments.
Features
Random Activity Generation
Simply provide the simulator with a set of nodes. SimLN will generate activity based on the topology of the network.
Configured Payment Flows
Define specific payment patterns to simulate the exact kind of traffic you need.
Cross-Implementation Support
Support for LND and CLN nodes, with work ongoing to add Eclair and LDK-node.
