The French company Shotgun, which manages online ticketing for artists and their fans, previously relied on Heroku but switched to Vercel as its frontend platform, allowing it to scale more efficiently during traffic spikes. With Vercel's serverless autoscaling, deployment branches that automatically provision upon each `git commit`, Edge Config for quickly configuring new waiting rooms, and Cron Jobs for simplifying setup, Shotgun can now focus on innovating and building products rather than spending time on DevOps. The company has also expanded its user base to the US and Brazil, relying on features like Edge Middleware and Vercel Analytics to fine-tune cookie handling and track site performance in real-time, enabling better optimization for these new markets.
