Riza

Riza belongs in the catalog because secure code execution has become one of the most important infrastructure gaps in AI applications. Once agents need to transform files, evaluate code, run scripts, or perform tool-like computation, teams quickly discover that the hard part is not writing the execution code. It is isolating it safely, governing runtime limits, and exposing it through a dependable API. Riza is directly in that lane. The public site positions it around secure isolated environments, custom runtimes, and execution APIs, which makes it a meaningful stack choice for agent builders rather than a generic developer utility.

It also deserves inclusion because the pricing page is both visible and crisp. Hobby is free forever with 100,000 requests per month, Pro is $250 per month with 1,000,000 requests included, and Enterprise is custom for larger or self-hosted deployments. The same page also publishes execution-time limits and custom runtime counts. That level of transparency is exactly what a serious catalog entry should reward because buyers can actually model whether Riza makes more sense than building sandbox execution infrastructure internally.
