Skyfire - Pros & Cons
Pros
- ✓KYA identity solves a real and growing problem — distinguishing legitimate autonomous agents from scraping bots without CAPTCHAs.
- ✓Spend limits, approval thresholds, and audit logs give users genuine control over what an agent can buy on their behalf.
- ✓Per-request / per-token / per-result billing matches agent usage shape far better than human-oriented monthly subscriptions.
- ✓Stablecoin settlement on the merchant side opens international micropayments that traditional card rails make prohibitively expensive.
Cons
- ✗Two-sided network problem — value depends on both agents and merchants adopting Skyfire; ecosystem traction is still early.
- ✗Crypto/stablecoin settlement is a feature for some buyers and a non-starter for others (regulated finance, compliance-cautious enterprises).
- ✗Take-rate and fee schedule are not publicly listed; budgeting requires a vendor conversation.
- ✗Regulatory landscape for agent-initiated payments is unsettled; compliance posture may shift as US/EU rules evolve.
E2B - Pros & Cons
Pros
- ✓Strong isolation via Firecracker — safe enough for fully LLM-generated code
- ✓150ms cold-start is fast enough for interactive chat-style agents
- ✓Drop-in ChatGPT-style Code Interpreter SDK with persistent Jupyter kernels
- ✓Desktop sandbox makes browser-use and computer-use agents practical
- ✓Production-proven (Perplexity, Hugging Face) and well-instrumented
Cons
- ✗Per-hour pricing can balloon for long-running autonomous agents
- ✗Pro tier only includes 20 hours/mo — most teams burn through it
- ✗Smaller per-sandbox resource limits than running on your own GPU box
- ✗No GPU access on standard sandboxes (use Modal or RunPod for that)
