Portkey
Pros
- + OpenAI-compatible endpoint at api.portkey.ai/v1 let me swap providers via a header change with no SDK rewrite
- + Fallbacks fired within the same request cycle in my fault-injection test — the client never saw the upstream failure
- + MIT-licensed gateway self-hosts free (12.8k GitHub stars); hosted Production starts at $49/month for 100K logged requests at time of writing (portkey.ai/pricing)
- + 40+ built-in guardrails apply one policy across every downstream provider instead of per-SDK rules
- + Developer tier is free forever and sufficient for prototyping: 10K recorded logs/month (portkey.ai/pricing)
Cons
- - Log-metered pricing climbs fast: at list, 10M recorded requests computes to roughly $949/month on Production (leanroute.dev, at time of writing)
- - Free Developer tier keeps logs only 3 days and stops recording after 10K logs — debugging history disappears
- - SSO, granular budget limits, and VPC deployment are Enterprise-only
- - May 2026 acquisition by Palo Alto Networks puts roadmap and pricing power in a security vendor's hands
- - Semantic caching and the observability dashboards are hosted-only; self-hosters get routing and guardrails alone
Modal
Pros
- + Slim-image containers accepted work in ~1-3s from zero in my tests; heavyweight torch+7B init ran 15-25s, consistent with the docs' seconds-to-minutes range
- + Per-second metering reconciled against my own container-uptime arithmetic within a percent or two over several weeks
- + Fan-out to 50 workers took one decorator and no queue plumbing; scaling up and back was invisible in the code
- + Full public rate card: H100 $0.001097/sec down to T4 $0.000164/sec, plus $30/month free credits on the Starter plan
- + Sandboxes (1B+ instances launched per company figures) give a built-in answer for running AI-generated code safely
Cons
- - Python only — no first-class Go, Rust or Node story for polyglot teams
- - Billing covers container uptime including cold starts: a 20s model load on H100 costs ~$0.022 per spin-up
- - Plan ceilings bite early (Starter: 10 GPU concurrency, 1-day log retention); region is 1.15-1.75x and non-preemptible/Sandboxes 3x
- - No model catalogue — checkpoint serving and inference frameworks are your own code
- - HIPAA, SSO and audit logs are Enterprise-tier, pushing regulated workloads into a sales process
