Business context
The Contentstack team runs a massive content delivery and experience platform, serving APIs behind a global CDN for third-party websites, mobile apps, and e-commerce systems. Every request hits their API with a unique key, and their team needs to trace errors, group by status codes, and export logs to customers.
Before and after Bronto
| Before Bronto | After Bronto |
|---|---|
| 40TB monthly ingestion cap | Boosted ingestion to 60TB monthly |
| 30+ minute query times (when they worked at all) | Complex multi-day queries return in seconds |
| Dashboards that routinely failed | Faster, more reliable dashboards (sub-second over terabytes of data) |
| Constant budget pressure | Cut their logging bill in HALF, while adding more CDN workloads to Bronto |
| Slow performance for queries on behalf of customers | Built reliable log exports for their customers |
How Bronto helped
Bronto serves as Contentstack's unified logging layer for high-volume CDN workloads, starting with Fastly logs and expanding to include Cloudflare data. Bronto enables Contentstack to store significantly more log data over extended periods — something that was previously cost-prohibitive.
Extended retention unlocks new value: with 12-month retention (compared to their previous 2-week window), Contentstack's teams can now analyze months of historical data to understand business-critical patterns. They're tracking customer API latency trends over time, identifying seasonal performance variations, and building comprehensive reports that inform both operational and strategic decisions.
From operational to analytical: this extended data access has opened up use cases beyond immediate troubleshooting. Contentstack performs business-level analysis directly from their log data, examining customer usage patterns and API performance trends that were previously slow and cumbersome to reveal.
AI-powered efficiency: as a design partner, Contentstack is helping shape Bronto's AI capabilities, including natural-language query features that reduce time-to-insight and improve team efficiency during incident response.
Benchmarks at Contentstack scale
- Typical queries span 635GB of CDN data and return in 2.2 seconds on average (vs. 30+ minutes previously)
- Large queries (1–5TB) filtered for rare events like specific HTTP error codes or endpoint failures return in under 900ms
- Multi-terabyte queries with heavy aggregation (e.g. grouping by customer ID across months of API logs) complete in around 4 seconds
It's a night and day difference to our previous logging provider. Bronto typically returns results in seconds, while our old vendor took over 30 minutes and frequently failed to render visualizations. Bronto has come a long way with everything from usage to UI. Our users are getting what they're looking for.
