PickDuel checked this company on its own initiative. Checked 22 Sept 2026. Based on the 20 Trustpilot reviews and 2 web discussions we could read (1 Nov 2022 to 2 Jun 2026). Review sites over-represent people with strong experiences, especially billing and support problems, so this shows what reviewers say, not every customer. The company's promise is quoted word for word from its own site. An AI groups reviews by topic; the counts and the verdict are fixed rules. How the Reality Gap works

SCORE BREAKDOWN
- Positioning23/25
Clearly targets developers building AI agents and modern apps with hardware-isolated Linux environments that sleep to zero when idle.
- Product clarity20/20
Explicitly details primitives like Sprites and Machines alongside use cases such as coding agents, MCP servers, and untrusted code execution.
- Trust16/20
Displays prominent tech customers like Supabase and Replicate with detailed case studies, though corporate office and leadership details are absent in the pages we read.
- Conversion16/20
Multiple clear 'Start for Free' and 'Sign Up' CTAs provide a direct, low-friction entry point for developers.
- Pricing clarity15/15
Supplies granular, transparent pricing broken down by second-metered VM sizes, hourly Sprites compute, storage, and support plans.
