AWS Lambda
Pros
- + Zero idle cost with a free tier that covers small products: 1M requests and 400,000 GB-seconds monthly
- + Graviton pricing at $0.0000133334 per GB-second undercuts x86 by roughly 20%
- + Automatic multi-AZ scaling with a 99.95% per-region SLA and no capacity planning
- + Deep event integration across AWS services, with three form factors (Event/Web Functions, MicroVMs)
Cons
- - Per-request and GB-second pricing gets expensive against committed compute at steady high utilization
- - Cold starts — hundreds of milliseconds to seconds depending on runtime — with provisioned concurrency as an extra meter
- - 15-minute execution limit and payload caps make it wrong for long-running batch work
- - AWS-specific event plumbing creates real lock-in; distributed event chains are hard to debug
Lagon
Pros
- + Genuinely open source (AGPL-3.0) with a self-hostable full stack
- + Sound architecture: Rust runtime on V8 isolates with WinterCG-style Web APIs
- + Everything an edge platform needs was in the box: CLI, cron triggers, custom domains, rollback, logs
- + Free while it existed — no bill to model
- + The team and technology now sit inside Vercel, so the ideas live on
Cons
- - Discontinued: acquired by Vercel, cloud shut down, repo archived March 2026
- - Never left alpha — breaking changes and missing features were documented by the project itself
- - No SLA, no published pricing, no support channel
- - lagon.app still advertises a live product with no shutdown notice
- - Self-hosting an unmaintained V8-based runtime is a security liability
