13 top open-source tools to Supercharge web development in 2025🎉 🚀

#webdev #javascript #programming #beginners

As a backend developer, I've seen and used countless tools. But some truly stand out in making our lives easier.

So, I made a list of 13 open-source tools to help supercharge your web development journey in 2025.

1. Composio: The Integration platform for AI agents

AI is eating the software; in 2025, a large part of web development will also include AI capabilities. However, given their complex OAuth flows, integrating applications like GitHub, Slack, and Gmail into AI agents can be challenging.

Composio solves this. It lets you integrate over 250+ applications from various categories like Calendly, Jira, and Drive to make complicated automation.

Here's a small example of using an agent to star a repo on GitHub using Composio.

Getting started with it is very easy.

npm install composio-core openai
Enter fullscreen mode Exit fullscreen mode

Connect your GitHub Account

import { Composio } from "composio-core";

const client = new Composio({ apiKey: "<your-api-key>" });

const entity = await client.getEntity("Jessica");
const connection = await entity.initiateConnection({appName: 'github'});

console.log(`Open this URL to authenticate: ${connection.redirectUrl}`);
Enter fullscreen mode Exit fullscreen mode

Initialize Composio and OpenAI

import { OpenAI } from "openai";
import { OpenAIToolSet } from "composio-core";

const openai_client = new OpenAI();
const composio_toolset = new OpenAIToolSet();
Enter fullscreen mode Exit fullscreen mode

Fetch GitHub actions and pass them to the LLM

const tools = await composio_toolset.getTools({
actions: ["github_star_a_repository_for_the_authenticated_user"]
});

const instruction = "Star the repo composiohq/composio on GitHub";

const response = await openai_client.chat.completions.create({
model: "gpt-4o",
messages: [{ role: "user", content: instruction }],
tools: tools,
tool_choice: "auto",
});
Enter fullscreen mode Exit fullscreen mode

Execute the tool calls.

const result = await composio_toolset.handleToolCall(response);
console.log(result);
Enter fullscreen mode Exit fullscreen mode

The documentation provides more on Composio, its work, and important concepts for making capable production-ready agents.

2. Hono: An Ultrafast, Versatile Framework for Edge Computing

Hono is a lightweight and exceptionally fast web framework that runs on various JavaScript runtimes. This makes it suitable for use with Deno and particularly well-suited for edge computing environments like Cloudflare Workers.

Here's a simple Hono application:

import { Hono } from 'hono';

const app = new Hono();

app.get('/', (c) => c.text('Hello Hono!'));

export default app;
Enter fullscreen mode Exit fullscreen mode

Hono's minimal size and speed make it a strong contender for building APIs and applications in resource-constrained environments.

3. Val Town: An Innovative Social Platform for Sharing and Running Code

Val Town offers a unique social coding environment where developers can write, share, and execute small TypeScript or JavaScript code snippets. These snippets can be run as serverless functions or scheduled tasks (cron jobs), fostering a community-driven approach to code execution.

Here's an example of a simple function in Val Town:

export async function hello(name: string) {
  return `Hello, ${name}!`;
}
Enter fullscreen mode Exit fullscreen mode

Val Town provides an intriguing way to experiment with code, collaborate with others, and deploy small utilities without complex infrastructure.

            m("h1", {class: "title"}, "My App"),
        ])
    }
}
Enter fullscreen mode Exit fullscreen mode

Mithril.js boasts a small API surface area, making it easy to learn and master.

13. DiceDB: A new approach to in-memory database

Dice DB brings a fresh take on modern data storage with its “roll-based” partitioning for automated sharding and near-instant scalability. It’s lightweight and robust enough for serverless and edge deployments for high-volume workloads.

Setting up the DiceDB server
The easiest way to get started with DiceDB is using Docker by running the following command.

docker run -p 7379:7379 dicedb/dicedb --enable-watch
Enter fullscreen mode Exit fullscreen mode

The above command will start the DiceDB server running locally on the port 7379 and you can connect to it using DiceDB CLI and SDKs.

Build from source

git clone https://github.com/dicedb/dice
cd dice
make build
Enter fullscreen mode Exit fullscreen mode

The above command will create a binary Dicedb. Execute the binary, and that will start the DiceDB server.

I would like to suggest a paradigm-shift by using the full stack but ten completely data-driven, like with TSQL.APP
