WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
OVPsim would be another option: https://github.com/riscv-ovpsim/imperas-riscv-tests it's a commercial simulator, but a free version is available for RISC-V. Unlike Spike it's not open source. However as it's a commercial product it's likely to be more extensively tested than Spike (not hard as Spike has no tests!). Potentially you'd find it to be more robust with fewer bugs than Spike.
That said we used Spike as a reference simulator for verifying Ibex (RISC-V core I work on, https://github.com/lowRISC/ibex) and we run an extensive set of random programs through it comparing its execution to Ibex's and I've not come across any major issues.
