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.

JIterator features and specs

Questions & Answers

As answered by people managing Vercel and JIterator.

What makes your product unique?

JIterator's answer:

Traffic as test cases, supporting automatic diff and automatic assert, eliminating the cost of data preparation and assert writing, achieving lower-cost automated testing.

Why should a person choose your product over its competitors?

JIterator's answer:

Automated traffic recording and replay technology revolutionizes testing efficiency and accuracy. Streamline your testing processes, shorten iteration cycles, and ensure continuous software quality improvement.

How would you describe the primary audience of your product?

JIterator's answer:

Medium to large enterprises with the Java technology stack or small enterprises with special requirements for stability

What's the story behind your product?

JIterator's answer:

In 2015, to address the increasingly severe challenges of automated testing for Taobao's price calculation system, we developed a traffic testing tool suitable for Taobao's backend systems, inspired by Tcpcopy. With its help, the price calculation system has never had a failure since.

In 2016, we were tasked to support the largest reconstruction project in the history of Alibaba's transaction system: the middleware transformation project. To support core transactions, we improved the product and achieved fully automated Mock capabilities for downstream systems, ensuring the smooth implementation of the project. Later, recording and replay became the core safeguard for the transaction system.

As our reputation spread within the group, our product was adopted and used by more teams. By 2023, more than 7,000 systems had adopted the system for support and it had also supported hundreds of system reconstruction projects, including Ping An Bank externally.

Due to organizational strategy adjustments, the traffic testing tool no longer provides external services. We created JIterator to provide services to the public. It has also surpassed the original traffic testing tool in many aspects, surpassing its predecessor.

Which are the primary technologies used for building your product?

JIterator's answer:

Traffic recording and playback technology based on JVM-TI

Who are some of the biggest customers of your product?

JIterator's answer:

Alibaba Pingan bank

    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.

  • Best alternatives to Heroku in 2026
    Vercel is where JS-heavy Heroku apps land when the shape they really wanted was framework-native serverless, especially anything on Next.js. ISR caching, edge functions, image optimization, middleware, and the AI SDK all wire up automatically from the framework's build output, so the parts of the app Heroku was serving as HTTP handlers become serverless functions that don't pay for idle time. - Source: dev.to / about 18 hours ago
  • 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 / 18 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 / 19 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 / about 1 month 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 2 months ago
