Use Case Recommendations
Best for: Riza
Riza is an isolated runtime that lets LLMs execute the code they write without putting your systems at risk. The pitch is compressed into four words on the homepage — AI writes code, Riza runs it — and the product is deliberately narrow: it is a code-execution API, not an agent framework. Integration is a few lines in Python, TypeScript, Go or cURL: add the SDK, call command.exec with the code and language, and read stdout back. Three properties define it. Security isolation means untrusted model-generated code never touches your production environment or secrets, and you configure environment variables and network access separately for each execution rather than granting a standing sandbox broad permissions. Cold starts are effectively eliminated — code begins executing under 10ms after Riza receives it, with no sandbox provisioning or deploy step, which is what makes it usable inside a synchronous agent loop rather than as a background job. And the design is API-first, with RESTful endpoints and SDKs across the main languages. Custom runtimes let you pre-install dependencies. The free tier includes custom runtimes and Discord community support; the Pro tier at $250/month covers a million requests for growing startups.
Ideal use cases:
- •Teams or individuals who need execute llm-generated code in a secure isolated environment
- •Teams or individuals who need under 10ms to start executing — no sandbox provisioning or deploy
- •Teams or individuals who need per-execution configuration of environment variables and network access
- •Teams or individuals who need api-first with sdks for python, typescript and go plus curl
- •Anyone focused on code-execution workflows
- •Anyone focused on sandbox workflows
Best for: Tenki Cloud
Tenki Cloud sells three pieces of infrastructure to teams building with coding agents, and the connecting thread is that each replaces something an agent workflow currently waits on. Tenki Sandbox gives disposable full Linux VMs that boot in under two seconds and bill per second, so an agent can run untrusted or generated code in a real machine rather than a constrained runtime, driven from a CLI or Go, TypeScript and Python SDKs. Tenki Runners are drop-in replacements for GitHub-hosted Actions runners, migrated by changing the runs-on label in a workflow file, and claimed to be about 30% faster and up to 60% cheaper. Tenki Code Reviewer runs AI review on every GitHub pull request. The detail that signals who the product is really for is that the homepage is written partly as onboarding instructions addressed to AI agents, with a published skill file at /skill.md and a single tenki onboard command, so an agent can set up its own account without a human walking the flow. Pricing gives every plan monthly credits with usage billed only beyond them, and a startup programme offers up to $50K in credits and grants. Runners migrate by editing one line in a workflow file, which makes the cheapest thing to try also the easiest to reverse if the numbers do not hold up.
Ideal use cases:
- •Teams or individuals who need disposable linux vms booting in under two seconds, billed per second
- •Teams or individuals who need drop-in github actions runners via a runs-on label change
- •Teams or individuals who need ai code review on every pull request
- •Teams or individuals who need go, typescript and python sdks plus a cli
- •Anyone focused on sandbox workflows
- •Anyone focused on ci-cd workflows
