RUM for Small Business 2026
If your site does under 100,000 sessions per month, you can run production RUM for free or for under $100/month. Here's the free-vs-paid comparison.
Direct answer
What's the cheapest viable RUM setup for a small business site?
Cloudflare Web Analytics is free with no cap if you only need Core Web Vitals. For errors + replay, Sentry's free tier (5K errors + 50 replays/month) is sufficient for early commercial use. For commercial workloads under 100K sessions/month with no replay needed, Raygun Basic at $80/year is the cheapest published paid tier.
The free options
- Cloudflare Web Analytics — free, unlimited, no published cap. Core Web Vitals only. No replay, no errors, no custom events. Best fit when Cloudflare proxies the site.
- Sentry free tier — 5,000 errors + 50 replays + 10,000 transactions per month. Works for hobby and pre-launch.
- Fullstory free tier — 30,000 sessions/month with 12-month retention. Most generous free tier in the matrix.
- Grafana Faro self-hosted — open-source, zero SaaS cost, infrastructure cost only.
- Raygun free trial — 5,000 sessions/month, time-limited.
The cheapest paid tiers
- Sematext Experience Basic — $9/month for 5,000 sessions, 7-day retention.
- Raygun Basic — $80/year ($6.67/month) for 100,000 sessions/month, 60-day retention, no replay.
- Sentry Team — $26/month annual ($312/year) including modest replay allowance.
- Atatus Startup — $49/month for 100,000 page views with APM + RUM + Logs bundled.
- LogRocket Core — $69/month for 10,000 sessions including pixel-perfect replay.
Decision flow by need
- Only need Core Web Vitals? Cloudflare Web Analytics, free.
- Need errors + a bit of replay for debugging? Sentry free tier or Team plan.
- Need replay-first product? Fullstory free 30K (if within limit) or LogRocket Core $69/mo.
- Need cheap commercial RUM without replay? Raygun Basic $80/year.
- Need bundled APM + RUM at small scale? Atatus Startup $49/month.
What to avoid for small business
- Datadog RUM — no free tier and per-session pricing scales aggressively. Below 1M sessions/month, the cost isn't justified by feature breadth advantage.
- Catchpoint — $10K/yr floor is enterprise pricing.
- Akamai mPulse — quote-only, enterprise-only.
- Splunk RUM — enterprise-bundled inside Observability Cloud.
