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
Fastly Compute@Edge
Pros
- + Per-request WebAssembly sandboxes with very fast startup — effectively no cold starts
- + Generous free allowances: 10 million requests and 100 million vCPU-milliseconds free every month
- + Billing by requests and vCPU only (duration meter removed for new purchases) rewards efficient code
- + Runs globally on Fastly's 100+ PoP network with HTTP/3, IPv6 and DDoS mitigation included
- + Official SDKs for Rust, JavaScript, Go and C++, plus KV Store, Secret Store, Object Store and Fanout
Cons
- - WASM compilation and capability-based sandboxing add real tooling friction versus mainstream serverless
- - Free-trial state on first deploy, account-type-dependent limits, and two legacy pricing regimes complicate planning
- - Edge state stores use Fastly-specific APIs — no S3-compatible or Redis-compatible interface
- - Outside the official SDK languages, you are a pioneer; long-running workloads do not fit
- - Production use pushes toward a sales conversation rather than pure self-serve
