Inngest
Pros
- + Real free tier ($0, no card, 50k executions) that pauses at quota instead of billing overage
- + Durable execution without operating queues, brokers, or worker fleets — code stays on your infra
- + Open-source, self-hostable server as an exit path from vendor lock-in
- + Strong SDK coverage (TypeScript, Python, Go, Kotlin) and developer tooling (dev server, replay, traces)
- + Per-run economics are excellent at volume on Pro ($99/mo for 1M executions)
Cons
- - Execution billing counts every step (runs x steps+1), so step-heavy workflows burn quota fast
- - Steep free-to-Pro jump to $99/mo once free caps (5 concurrent steps, 24h traces) bite
- - No published uptime SLA below enterprise agreements
- - Not infrastructure — you still need somewhere to run your code
- - Plan walls on workspaces, apps, and trace retention push growing teams upward quickly
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
