Loadster is a cloud-based load testing and synthetic monitoring platform for engineers who want to know how their applications behave under real traffic.

Tests run with three types of bots: Protocol Bots for HTTP testing, headless Browser Bots that render full pages and execute JavaScript in real Chrome browsers, and Playwright bots for when you want to use Playwright JS directly.

Loadster scripts can be recorded from Chrome or Firefox with the Loadster Recorder extension, edited in a built-in editor with variables, datasets, and shared includes, and then replayed from multiple cloud regions.

Each test run returns detailed page timings (TTFB, FCP, LCP, CLS, etc) alongside resource waterfalls, screenshots, and full traces you can step through in a self-hosted trace viewer. Tests scale from a handful of virtual users (bots) to hundreds of thousands across distributed cloud engines without you provisioning anything.

The same scripts can be set up as monitors that run on a schedule from chosen regions. Notification policies route incidents to email, SMS, voice, or integrations like Slack and PagerDuty. Projects, roles, and shared test history keep teams aligned on what passed, what failed, and what changed.

Pricing is usage-based via Loadster Fuel, with 50 free units on sign-up and no credit card to start.

Possible disadvantages of Vercel

  • Cost
    While Vercel offers a free tier, the pricing can become expensive for larger projects or enterprises, particularly if they require more bandwidth, build minutes, or advanced features.
  • Serverless Limitations
    Serverless functions on Vercel have limits on execution time and computational power. This can be a constraint for compute-heavy tasks or long-running processes.
  • Vendor Lock-in
    Deploying heavily integrated projects with Vercel's proprietary features may make it difficult to migrate to another platform without significant rework.
  • Limited Backend Customization
    While Vercel supports serverless functions, it does not offer the same level of backend customization and control as traditional server hosting environments.
  • Learning Curve for Beginners
    Although easy deployment is a pro, beginners might find it complex to understand concepts like serverless architecture, environment variables, and project structure in the beginning.
  • Limited Language Support
    Vercel primarily supports JavaScript/TypeScript for serverless functions, potentially limiting the use for developers who prefer other programming languages for backend development.

    We leverage Vercel For Next JS hosting

    We have been using Vercel to host some of our internally developed apps that help our team run our operations on Vercel and have found it to be a very developer friendly platform. With our apps built in Next JS it is a natural fit and the dev op pipelines can quickly and easily be configured. As these are internal apps used by our team they don't need to support huge traffic volumes so pricing has been affordable for us.

  • Friday Fixes: The Fix That Wasn't
    What went wrong: The security commit added a Content-Security-Policy Header with connect-src 'self' https://*.public.blob.vercel-storage.com. The Vercel Blob SDK's client-side upload() makes a PUT to Https://vercel.com/api/blob. That domain wasn't in connect-src. The browser silently blocked the request. - Source: dev.to / 11 days ago
  • How to Get Your First Tool Online
    A host: A host is really just a computer that stays powered on and connected to the internet with a public address of its own. When a visitor types in the app's address, their browser sends a request across the internet to that machine, the machine runs the code, and it sends the finished page back. A laptop was quietly doing both jobs during the build, the server and the only visitor allowed in; a host is that... - Source: dev.to / 13 days ago
  • Launching BabyChain: durable image and video model chains on AWS Aurora and Vercel
    The short version is this: BabyChain lets you design a ComfyUI-style media chain on a canvas, then call that same chain from product code as POST /api/v1/chains/runs. Every step executes through provider APIs with server-side credentials, every state transition persists to AWS Aurora, and Vercel functions stay stateless. - Source: dev.to / 25 days ago
  • How I Run 3 Production AI SaaS on $5/Month of Hosting
    My recommendation: if you're bootstrapped and cost matters, start on Cloudflare. If $15-25/month genuinely doesn't affect your runway, start on Vercel for the DX. The break-even is not where the marketing makes it sound โ€” it's much earlier than you'd guess. - Source: dev.to / about 1 month ago
