Sumidata vs FullStory
FullStory is a mature digital experience platform sold through enterprise sales. Sumidata is a focused session replay + AI analytics product with public self-serve pricing. Here's an honest read on where each fits.
01TL;DR
The short version before you scroll.
Pick FullStory if you're an enterprise buyer, you need mobile SDKs, and your procurement is fine with a sales cycle and annual commitment. Pick Sumidata if you want public pricing, a one-line install, and an AI Analyst you can try today without talking to anyone — especially if your users are on the web.
02Feature comparison
Feature-by-feature. Everything here is verifiable in our /docs — no marketing claims we can't back.
| Feature | Sumidata | FullStory |
|---|---|---|
| Pricing | Public self-serve. Free (50K sessions), Pro $100/mo, Business $200/mo, Scale $500/mo. | Contact sales. Enterprise annual contracts, no public tier. |
| Install | One <script> tag with data-project-id. Async loader ~2 KB gzipped. | Script tag + implementation review with a customer-success team on paid tiers. |
| Session replay | rrweb-based. Timeline synced with console logs and product events in one viewer. | Proprietary capture engine. Mature, deep filtering, frustration signals. |
| AI natural-language queries | AI Analyst ships on every plan. Natural language → ClickHouse SQL, chart + explanation, SQL is inspectable. | "StoryAI" — assistant on higher tiers. |
| Mobile SDKs | Not available. JavaScript script tag only. | iOS and Android SDKs. |
| Multi-tenancy | Native. Tenants → projects → users, OTP email login, unlimited seats on every plan. | Workspace / org model on enterprise tiers. |
| Retention | 1 month (Free) → 3 / 6 / 12 months as plan scales. | Negotiated per contract. |
03Where each tool fits
Where each tool genuinely shines — not marketing theatre.
- Web-only product, no mobile apps to instrument.
- You want to evaluate on a real project this afternoon, without a sales call.
- Natural-language questions over the data matter to your team (product, growth, support).
- Multi-project / multi-tenant setup is a first-class need, not an enterprise upsell.
- Transparent, predictable monthly billing beats annual commits for you.
- You need native iOS / Android session capture alongside web.
- You're at enterprise scale and want dedicated customer success and onboarding.
- Procurement prefers negotiated annual contracts over self-serve card payments.
- You've standardised on FullStory integrations (Salesforce, Slack, Zendesk) already.
04The pricing honesty check
The only part we can quote exactly — because ours is public and theirs isn't.
Sumidata's plans are published on /pricing. Free is $0 and gives you 50,000 sessions a month, 1-month retention, and unlimited AI queries — enough to evaluate the product on a real side-project. Paid plans are $100, $200, $500/month with a 14-day free trial. Billing runs through Paddle (credit card or PayPal), no annual commitment required.
FullStory does not publish prices. Every quote is negotiated through their sales team, typically as an annual contract. That's normal for enterprise SaaS, but it means you can't compare dollar-for-dollar here — we're not going to guess their numbers.
05What Sumidata doesn't do (yet)
Things we don't do yet — said out loud so you can plan around them.
- Mobile SDKs — no iOS / Android / React Native capture. Web only.
- Heatmaps — scheduled for a full rebuild; not usable right now.
- Feature flags, surveys, dedicated issue management — not on the roadmap.
- SOC 2 / HIPAA — we reference the controls but are not formally certified yet.
