Last month my Vercel bill hit $400. The month before? $50. Same traffic, same app. That's when I realized Vercel's "predictable" pricing is anything but.
The final straw was when our Next.js app started hitting serverless function timeouts during a Black Friday sale. 10-second limit, no exceptions, no workarounds. Our checkout process was failing and Vercel support basically said "maybe try breaking your logic into smaller functions."
The Real Problems Nobody Talks About
Bill Shock is Real
Your first Vercel bill will be reasonable. Then you'll get some actual traffic and wonder why you're paying $200 for bandwidth that costs $20 on Cloudflare. That calculator on their pricing page? Pure optimistic fiction that assumes your app stays as popular as a MySpace profile in 2025.
Serverless Functions Are A Trap
10-second timeout means you can't process payments, send emails, generate reports, or do basically anything useful. Want WebSockets? Too bad. Need background jobs? Doesn't exist. Real-time features? Hope you enjoy polling. Even their Pro plan caps at 5 minutes, which is barely enough for real work. Meanwhile, platforms like Railway handle long-running processes without arbitrary timeouts.
Next.js Lock-in is Sneaky
They get you hooked with ISR and edge functions, then you realize these don't work anywhere else. Migrating means rewriting half your app because you used Vercel-specific APIs. Even deploying Next.js on other platforms requires understanding their vendor-specific optimizations.
Enterprise Support is a Joke
$20k minimum for custom contracts. Their "Pro" support is email-only with 24-hour response times. When your app is down, 24 hours feels like 24 years. Compare that to Railway's Discord where actual engineers respond in hours, or Render's support that actually helps instead of suggesting you "try redeploying."
Here's what finally pushed me over the edge: during a critical deployment issue, I lost a full day of productivity because their dashboard was buggy and showed conflicting information. The deploy logs said success, the functions said they were deploying, but the site was serving a 404. Support's response after 8 hours? "Try redeploying."
That's when I started researching alternatives in earnest. Turns out there are platforms that don't actively try to screw you over - they just want to host your app and charge you fairly for it. Revolutionary concept, I know.
