Why people look for alternatives to sandboxd
The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.
- Docker-only isolation raised unresolved HN concerns versus MicroVM-grade boundaries.
- Default install previews are localhost or sslip.io, not public URLs.
- No Kubernetes, no HA, no managed scaling — you own the on-call burden.
- External review data is thin: no Reddit, Stack Overflow, or App Store feedback.

In fairness: users also consistently praise one command install on a $20 vps replaces per-seat managed sandbox saas bills, and per-sandbox docker containers with filesystem and memory limits keep tenants separated. A complaint list is not a verdict — see the full picture on the sandboxd page.
