Project Overview: I am looking for a developer to build a custom browser extension for the game Slither.io. The goal of this project is to recreate the functionality and features of the classic "Slither X" mod, ensuring it is compatible with modern browser standards (Manifest V3). Project Goals & Requirements: I need an extension that allows for custom client-side modifications, specifically focusing on: Custom Skin Support: The ability to inject and display custom snake skins (e.g., specific Minecraft-themed textures) locally within the game. HUD/UI Features: Recreating the classic HUD elements that were present in the original mod, such as custom overlays or game information displays. Compatibility: The extension must be built using modern web standards (Manifest V3) to ensure it runs correctly on current versions of Chrome and Edge. How to Reference Features: Because the original "Slither X" mod is no longer actively maintained, I have identified exactly what I need by reviewing classic gameplay videos. You can see the specific skin designs and HUD layouts I am looking for by searching YouTube for "Slither X gameplay" and "Slither X mod showcase." These videos will serve as the visual reference for the features, skin styles, and interface layout that I need recreated. Technical Expectations: Please provide clean, well-commented code. The extension must be designed to be loaded as an "unpacked" extension for testing purposes. I am looking for a developer who can handle image injection and manipulate the game's canvas elements to display these custom assets correctly. Deliverables: A complete set of extension files (e.g., [login to view URL], [login to view URL], etc.). Documentation on how to load and use the extension locally. Call to Action: If you have experience with browser extension development or game modding, please reach out. I am happy to provide further details or discuss the project requirements. Please let me know your estimated timeline and how you plan to approach the skin injection logic. A Few Tips for Your Freelancer Post: Be Specific: Freelancers do better when they have clear instructions rather than vague orders. Use Milestones: If the project is large, ask the developer to break it into small "milestones" (like getting the HUD working first, then the skins) so you can approve the work as it progresses. Communication: can i have frequent check-ins to make sure the project stays on track.

I am also well-versed on the use of Manifest V3 for Chrome and Edge compatibility, guaranteeing your extension will run smoothly on current browsers. Moreover, my track record in understanding client requirements from the get-go ensures we work together cohesively with minimal back-and-forth. A large project like this can be overwhelming - but by leveraging my project management skills, I can establish milestones that break it down into manageable tasks, focusing on critical aspects like getting the HUD elements correct first before proceeding to custom skins. This process helps us approve the work as it progresses, making your vision a tangible reality more efficiently.

Hi there, I can build a Manifest V3 browser extension that recreates the classic Slither X experience with custom skin injection, HUD elements, and clean, well-commented code. I can provide an unpacked extension, documentation, frequent check-ins, and work with milestones. My plan is to recreate the HUD first, then implement the skin injection logic by modifying the game's canvas rendering while ensuring compatibility with Chrome and Edge. Do you already have the custom skin images, or should I recreate them from the reference videos? I have strong experience with JavaScript, HTML, CSS, Chrome extensions, canvas manipulation, frontend development, Node.js, React, and full stack web applications. I can deliver high-quality results and start immediately once we finalize the plan. Let's discuss the details via chat. Best regards, Malix

Hello! I have experience developing Chrome/Edge extensions and client-side web applications, and I can build a Manifest V3 extension that recreates the Slither X experience while keeping the code clean, documented, and easy to maintain. I'll implement the custom HUD, local custom skin support, and canvas/image injection based on your reference videos, with compatibility for current Chrome and Edge versions. Development will be milestone-based (HUD → skin injection → testing → polish), with frequent progress updates and demos so you can review each stage. I'll also provide complete source code, setup documentation, and instructions for loading the extension locally. Estimated timeline: 1–2 weeks, depending on feature complexity.

Hi, The extension can be rebuilt as a Manifest V3 project while preserving the client-side experience of the classic Slither X features, including custom skin rendering and HUD overlays. I'd structure the work in milestones so we can validate the HUD first, then implement the skin injection logic, and finish with compatibility testing on the latest Chrome and Edge versions, with regular check-ins throughout development. The approach would be to inject the required scripts through the extension, hook into the game's rendering where appropriate, and manage custom assets locally so they're easy to update. The code will be clean, well-commented, and organized into separate modules for the HUD, asset handling, and extension logic, along with documentation for loading the unpacked extension and maintaining it. One question before I estimate the timeline: should the extension only support your predefined custom skins, or would you like a simple interface to import and switch between multiple skins locally? Once we confirm that, I can break the project into milestones and get started immediately. Regards, Mahad Sheikh

Is the main issue recreating the classic "Slither X" mod, or are you mainly trying to achieve a modern, user-friendly browser extension? I’ve developed browser extensions that integrate custom features and enhance gameplay experiences. The goal here is to ensure smooth skin injection and a responsive HUD that elevates the player's interaction with Slither.io. Expect clean code and clear documentation to make future updates a breeze. In a recent project, I built a Chrome extension that improved user engagement by 30% through custom features, using technologies like Manifest V3. You can check out my work here: https://www.freelancer.com/u/taskra. Want me to get the first version moving today?

Hi, Have you already identified which Slither X features and HUD behaviors need to be replicated from the reference videos, and should the skin injection system support multiple local texture packs with seamless switching while remaining compatible with future game updates? You need a Manifest V3 browser extension that recreates the classic Slither X experience with custom skin injection, HUD overlays, and reliable compatibility on modern Chrome and Edge browsers. I'll build a clean, modular extension with documented code, implement canvas-based asset injection for custom skins, recreate the HUD from your references, organize the work into milestones with frequent progress updates, and provide complete setup documentation for local unpacked testing to keep future enhancements straightforward. Looking forward to discussing the details!

Hello! I see you're looking for a developer to recreate the classic Slither X mod as a modern Manifest V3 browser extension. The goal here is to build a fully functional extension that supports custom skins and HUD overlays, compatible with current Chrome and Edge browsers. A common challenge with game modding extensions is ensuring the skin injection logic works seamlessly with the game's canvas rendering without breaking updates. What usually matters most here is precise manipulation of canvas elements and efficient image injection. The tricky part is often in maintaining performance while adding custom overlays. My approach would involve setting up a clean, modular codebase with well-commented files. I focus on building the skin injection system first, then layering the HUD features on top. I have worked on similar browser extension projects where I implemented custom asset injection and canvas manipulation, leading to smooth, reliable mod functionality. A few questions to better understand the scope: Q1 – Do you have specific skin textures or HUD layouts from the YouTube references you'd like prioritized? Q2 – How do you envision the balance between recreating the original mod features and adding new improvements? Q3 – Are there specific performance considerations you want to ensure for the extension? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.
