Case Study: Dune achieves zero screenshot failures with Browserless

Dune cuts screenshot failures from 10% to zero with Browserless

Dune, a provider of onchain data, faced a significant challenge with its self-managed browser infrastructure failing under unpredictable traffic loads. This resulted in a roughly 10% failure rate for the screenshots powering its dashboard previews and chart visualizations, leading to customer complaints. The vendor, Browserless, provided a solution using its Hosted Chromium pool and Puppeteer over WebSocket service to handle this critical rendering pipeline.

By implementing Browserless, Dune migrated its infrastructure with just a few lines of code. The solution brought the screenshot failure rate down to zero, eliminating all customer reports. Additionally, Browserless allowed Dune's engineering team to run 30-40 end-to-end tests in parallel on CI, improving release quality without maintaining dedicated test infrastructure.
