Replicate
Pros
- + Thousands of callable models with one HTTP request; custom models via Cog containers
- + Per-second billing with scale-to-zero: no idle charges on public models, failed runs free
- + Hardware range from T4 to H100 and multi-GPU configurations up to 8x H100
- + Model version pinning keeps community updates from silently changing outputs
- + Strong SDKs, webhooks, and a web playground for evaluating models before coding
Cons
- - Per-second GPU pricing gets expensive at sustained high utilization
- - US-only infrastructure: no region selection, no EU data residency
- - No published uptime SLA and no SOC 2/ISO certifications on record
- - Cold starts on large models can run to minutes
- - Prepaid credit model: credits expire, are non-refundable, and runs halt at zero balance
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
