Google Cloud Functions
Pros
- + 2 million free invocations per month, permanently, per billing account
- + Published 99.95% uptime SLA with 10/25/50% financial credits
- + 2nd gen on Cloud Run infrastructure: concurrency, Eventarc triggers, traffic splitting, GPU access
- + First-class Firebase, Pub/Sub, Cloud Storage, and Secret Manager integration
Cons
- - GCP lock-in: events, IAM, and deployment are Google Cloud objects
- - Gen 1 / gen 2 split means two pricing models and two capability levels in one product
- - Costs scale with abuse and bugs — every failed invocation is billed, no per-function spend cap
- - Container image storage (Artifact Registry) bills separately even within the free tier
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
