JSON Server features and specs

  • Ease of Setup
    JSON Server can be set up quickly with minimal configuration, making it ideal for prototyping and rapid development. It allows developers to have a fully functioning REST API within minutes.
  • RESTful API
    It provides a standard RESTful API out of the box, allowing developers to perform all CRUD operations. This is helpful for simulating a real-world server while testing client-side applications.
  • Customization
    JSON Server supports middlewares, routes, and custom rules, allowing developers to customize the behavior and structure of the API to better suit their needs.
  • Fakes Backend Data
    It's great for simulating backend responses without needing a real backend setup, useful in front-end development to test components and interactions.
  • Lightweight
    As a lightweight server, it requires fewer resources and is quite simple compared to setting up a full-fledged backend server.

Possible disadvantages of JSON Server

  • Not for Production
    JSON Server is designed for development and testing. It is not suitable for production use due to performance limits and lack of robust security features.
  • Limited Functionality
    While JSON Server is great for basic CRUD operations, it lacks advanced features like authentication, authorization, and complex querying.
  • Data Persistence
    Data is stored in a JSON file, and while this is convenient for testing, it is not suitable for applications that require persistent and scalable data storage.
  • In-memory Limitations
    Being an in-memory server, it may have issues with handling large datasets or complex data structures efficiently.
  • Manual Data Reset
    Any changes made to the JSON file while the server is running require manual resets or reloads to reflect in the API, which can be cumbersome during continuous development cycles.

Uptime Kuma features and specs

  • Open Source
    Being open-source means the source code is freely available for anyone to inspect, modify, and enhance, promoting transparency and community-driven development.
  • Self-Hosted
    Allows you to host the application on your own server, providing complete control over your data and infrastructure.
  • User-Friendly Interface
    Offers a clean and intuitive UI, making it easy for users to set up and manage uptime monitoring.
  • Customizable Notifications
    Supports multiple notification channels (e.g., email, Slack, Telegram) and allows customizable alert settings.
  • Multiple Monitoring Types
    Supports various types of monitoring including HTTP(s), TCP, and ICMP (ping), allowing for versatile use cases.
  • Resource Efficient
    Designed to be lightweight, ensuring it does not consume significant system resources.
  • Multi-Language Support
    Provides support for multiple languages, making it accessible to a broader audience worldwide.
  • Community Support
    Being part of a vibrant open-source community means you can get help and contribute to the project, which often results in rapid bug fixes and feature enhancements.

Possible disadvantages of Uptime Kuma

  • Self-Maintenance
    Requires the user to handle all aspects of server maintenance, including updates, backups, and security patches.
  • Limited Features Compared to Paid Solutions
    May lack some advanced features and integrations offered by commercial uptime monitoring services.
  • Initial Setup Complexity
    Can be complex to set up, especially for users who are not familiar with self-hosted solutions or lack technical expertise.
  • No Official Support
    Lacks official customer support, meaning users primarily rely on community help and forums for troubleshooting.
  • Scalability Issues
    May face scalability challenges when monitoring a large number of endpoints, requiring additional configuration and resources.
  • Dependency Management
    Requires careful management of dependencies and updates to ensure stability and compatibility, which may be time-consuming.

Uptime Kuma Reviews

Self Hosting Like Its 2025
Dockge is relatively new and created by the developer behind Uptime Kuma, which is a fantastic tool. Although it hasn’t yet reached the maturity of Portainer, Dockge truly excels in its simplicity. It’s also regularly updated, and the developer is prompt in addressing issues on GitHub.

  • Building a CRUD app with React Query, TypeScript, and Axios
    We'll be using json-server to create the REST API that we'll fetch data from. In the root of the project, create a db.json file with the contents. - Source: dev.to / 12 months ago
  • Full Stack To Do list, a step-by-step tutorial
    Our backend will be little more than a two-way translation layer between the database and the user interface (UI). Later in this post we will identify other responsibilities of a backend but our implementation will be kept simple to demonstrate the fundamental machinery and concepts. It is worth noting the backend comes in two parts, web server and application server. Both json-server and Express are able to... - Source: dev.to / almost 2 years ago
  • Improve Frontend-Backend development harmony with JSON-Server
    JSON-Server creates fake REST API with a minimum amount of configuration, it provides a simple way to create mock RESTful APIs and easily define the required endpoints, allows easy definition of the data schema in a JSON file and can serve as a reference for each figure in the project. - Source: dev.to / almost 2 years ago
  • Dictionary app
    I thought about usingJson Server (hosting the repo with the words on Github to begin with), Googlesheets, or maybe Firestore (i would prefer not to use it ,to avoid extra costs just in case it gets a reasonable amount of users). It isnt a big app so I just want a simple solution for storing the words and fetching them. Source: about 2 years ago
  • Playwright - Not just for Frontend
    First, I didn't create a backend API for this example, but I used a fake API to test. I created it with json-server and json-server-auth. They are two npm packages that use a JSON file as a database and expose the database in an API. You can find more about json-server in its documentation and about json-server-auth here. - Source: dev.to / over 2 years ago
