Development of a Chrome extension for automatic message sending

Budget: 5000 UAH Deadline: 30 days

I have extensive experience in developing browser extensions and automating complex web interfaces. I will create a reliable tool for you that will work stably and simulate the actions of a real user to minimize the risks of blocking.

What I offer:

Safe automation: I use randomized delays and pause simulation ("human" behavior), which is critical for protecting your account.

Flexible architecture: My code allows for instant modifications if the site updates its layout or changes the logic of message operations.

Full functionality: Working with lists, queues, real-time logging of results, and setting limits.

Clean code: The entire project will be accompanied by detailed comments so you can easily maintain it in the future.

My technical approach:

Using JavaScript (Vanilla or modern frameworks depending on the complexity of the site).

Reliable background operation (Service Workers).

Convenient interface for managing the mailing directly in the browser window.

Conditions:

Price and deadlines: Depend on the complexity of the target site (security systems, dynamic layout). I am ready to discuss the details after clarifying the resource.

I have ready examples of working automation systems. I am ready to start analyzing the site and implementing a prototype. Expand

Hello, I can develop a Chrome extension.
1. On which website will the extension work (to assess complexity and limitations)?
2. Is authorization already in the browser or does it need to be implemented within the extension?
3. What are the volume limitations (approximately messages per day)?
4. What is the deadline?

Hello! I have experience in developing extensions for Chrome based on Manifest V3 and automating web interfaces, so I would be happy to help with the implementation of this tool. I can prepare a stable extension for you with a concise control panel, where it will be convenient to configure text, recipient lists, and pauses. In development, I will focus primarily on security, using text input simulation and delay randomization to make actions appear natural to the site's algorithms. This will minimize not only the risks of account blocking but also the triggering of Anti-DDoS systems that may restrict access to the resource based on your IP address. You will receive transparent logging of each submission and clean code with comments. If my proposal interests you, please let me know which specific resource the work is planned for, so I can take into account the specifics of its protection in advance.

I have experience with Chrome Extensions, enhancing the convenience of admin management, and retrieving additional data via API for display in the admin panel.

Regarding automation, I wrote code in JavaScript that automatically opened a website, bypassed site blocking, simulated user actions, filled out forms, and submitted data.

For Chrome Extensions - there is a completed project on freelance in my profile.
For automation - it is in the work portfolio.

Write to me, and we will discuss your task.

Good day!
I have about 4 years of experience in developing Chrome extensions and automating websites, I can create a browser extension for mass messaging with all the specified features:

I will implement:
Authorization and interaction with the website
Mass messaging with configured delays (5-30 seconds)
Message limits per day
Log/report collection
Simple popup interface with all settings

Technically:
Full-fledged Chrome Extension (manifest v3)
Security - randomization of delays, user-agent rotation
Clean JavaScript + content scripts
Commented code
I understand the importance of avoiding blocks - I will implement natural behavior and account protection.

I am ready to discuss the specific website and details in private messages. Expand

Good day, making the extension is not a problem. The problem is protecting the site from spam. Which specific site are we talking about? Write the details in a private message.

Hello! I am ready to implement your project in pure JavaScript (Manifest V3). I will use chrome.storage to save settings and logs, as well as a background service worker for a stable sending queue. I have experience bypassing bot protection through interval randomization and event simulation. I will make the interface as simple and understandable as possible. I look forward to collaborating!

Hello!

I have experience (machine translation service, Instagram).

I am ready to start, but only after your approval of the technical assignment, which I will prepare and submit to you for approval, because there are more/less obvious pitfalls here. I want to clearly discuss them before I start working.

Sincerely,
Ruslan

Hello.

I can develop a Chrome Extension for mass messaging with a convenient internal control panel.

What I can implement:

* authorization and operation within the existing session of the website
* operation based on a prepared list of recipients or through built-in collection logic, if allowed by the website's structure
* mass sending of messages with customizable delays
* limiting the number of sends over a period
* logging of sent messages and statuses
* simple interface within the extension: message text, list of recipients, pause settings, start/stop

Technically, I can do this as a full-fledged extension for Google Chrome in JavaScript, with a clear code structure and comments.

I would like to note an important point: “completely safe operation without account blocking” cannot be guaranteed in advance, because it always depends on the anti-spam rules of the specific website, limits, frequency of actions, and the nature of the account. However, careful sending logic can be implemented: random pauses within a specified range, limits, phased operation, progress saving, and the most cautious usage scenario.

To provide an exact price and timeline, I need to understand:

* which specific website
* whether there are internal limits / captcha / anti-bot protection
* whether the mailing is based on a prepared list or if user collection is needed
* whether a template for a single message is needed or personalization

If the website has no heavy protection and no complex parsing, such a task can usually be implemented within a reasonable timeframe without overloading the architecture.

I have experience in automation, browser scripts, and developing tools for specific workflows, so I can provide not a “demo button,” but a working solution for a real scenario. Expand

Good day! We are from the SDEV team — a team of system developers and engineers. We understand your task and are ready to offer a solution for developing a Chrome extension that will ensure automatic message sending on the website.

Your project includes authorization, user collection, delay settings, logging, and other features. We have already implemented complex bot systems, for example, automated search and monitoring of cars on different platforms with instant notifications. Our experience allows us to create a reliable and secure extension that meets your requirements.

We use JavaScript and will ensure safe operation to avoid account blocking. The code will be commented for ease of further support.

If you have any additional wishes or questions, we will be happy to discuss the details.
