Convex vs Datadog: Pricing Comparison (2026)
Convex starts at $25/mo. Datadog starts at $18/mo. Datadog is $7/mo cheaper on the entry tier than Convex.
Reactive backend platform positioned as the alternative to Firebase for TypeScript developers who want end-to-end type safety + real-time subscriptions without configuring WebSockets. Distinctive per-developer pricing ($25/dev/mo Professional) instead of usage-based — predictable bills regardless of data volume or query count. Free tier is generous for solo projects. Popular with venture-backed startups building interactive AI/collaboration apps.
The dominant cloud observability platform (metrics, logs, traces, APM), publicly traded (DDOG), ~$45B market cap. Positioned as the alternative to New Relic + Splunk + PagerDuty stitched together. Distinctive for its notorious usage-based pricing that has surprised engineering teams with 6-figure monthly bills (Coinbase's leaked contract was ~$65M/year in 2022). Priced by seat + host + volume across 20+ meters. Popular with engineering teams; feared by finance teams.
