| Best for | TypeScript teams building real-time, collaborative or AI-agent applications who want to replace an assembled backend stack with one reactive platform and value developer velocity over infrastructure control. | Nobody as a hosted platform; self-hosters, researchers and forkers who want an AGPL-3.0 Rust/V8 edge-runtime codebase and are prepared to maintain it |

Convex
Pros
- + Replaces a whole backend stack — database, functions, sync, search, storage and auth — with end-to-end TypeScript type safety and ACID transactions
- + Generous economics for reactive apps: query/mutation compute free on serverless, plus a real free plan and pay-as-you-go Starter tier
- + All unit rates and per-tier limits published, including an honest 1.3x regional multiplier for EU and Canada
- + Core backend open-sourced (March 2024) with self-hosting option — genuine lock-in relief uncommon in this category
- + Well-funded ($110.5M through a $57M Series B in 2026), SOC 2 Type II, HIPAA compliant, with named production customers at real scale
Cons
- - Document model is not SQL — poor fit for Postgres estates, analyst workflows and BI tooling
- - Usage-based metering can surprise chatty clients; no hard spend caps on paid tiers
- - Support SLAs are a paid feature: 30-minute P1 response only in $1,000–$2,000/month premier tiers
- - TypeScript-first to the point of exclusion — a non-starter for non-TS teams
- - Self-hosting the open-source backend is an operational project most teams will only use as an escape hatch
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
