Built Cognitora.dev after getting frustrated with existing AI coding environments being either too limited, too heavy or too expensive. We're using Kata containers with the flexibility to run on either Firecracker or Cloud Hypervisor - letting us optimize for the best performance per workload.
Key differentiators from e2b/Daytona:
- True isolation with hardware-level security (not just Docker)
- Sub-3s cold starts vs 10-30s elsewhere
- Kata flexibility: Firecracker for ultra-fast startup, Cloud HV for heavier workloads
- Built-in AI context preservation across sessions
- Works with any LLM/model (not locked to specific providers)
The sandbox handles everything from simple scripts to full deployments. We're seeing devs use it for prototyping, code review with AI, and even production debugging in isolated environments.
Still early but would love feedback from the community.
What do you mean? I have been using e2b and daytona for the past year and they never took that long to boot. It usually takes less than 1 second for sandboxes to come live

As I use AI more and more in my project, i'm starting to explore the possibility of letting it run in a sandbox environment. Will check it out.

That's the exact use case we're targeting! Once you start giving AI more autonomy in your projects, sandboxing becomes critical. Lots of people are vibe coding in prod these days
