Unlocking the Power of Replit: A Modern Cloud IDE for Collaborative Coding
Artificial intelligence has simplified many complex processes, including software development. AI support and collaboration tools are now built into cloud IDEs (integrated development environments). In this article, we will tell you about one of the most popular platforms — Replit, which is used by over 30 million developers and designers. You will learn how to use Replit in different areas and what opportunities this AI IDE offers.
Replit’s Cloud-Based Development Environment
Replit is a cloud-based IDE that combines collaboration features with an online code editor enhanced by integrated AI models. The platform was founded by developers Amjad Masad and Faris Masad along with designer Haya Odeh in 2016.
The name Replit comes from REPL (Read-Eval-Print Loop) — a mode in which the program executes user commands and immediately outputs the result. The system was initially intended only for this purpose, but over time its functionality has become noticeably more complex.
A new page in the project's history began in October 2022 with the release of the AI assistant called Ghostwriter. It became one of the first such tools on the market and immediately attracted increased attention from the IT community.
The Replit Ghostwriter AI built into the IDE contained a set of functions for generating, editing, and explaining code. Users could interact with the virtual assistant via an online chat available on both PCs and mobile devices.
After the successful launch of its AI-powered code editor, Replit secured $97.4 million in Series B funding in April 2023, led by Andreessen Horowitz. This round raised the company’s valuation to $1.16 billion. In November of the same year, the startup received an additional $20 million in funding from Craft Ventures.

In September 2024, Replit introduced its flagship online editor with a built-in AI assistant, Agent, which became part of the updated IDE. The ability to generate and analyze code based on text queries made the platform suitable not only for experienced developers but also for those who are mastering coding for beginners online.
To accommodate different user needs, Replit offers a flexible selection of pricing plans:
- Starter — free access, includes trial access to Agent and up to 10 public apps with temporary links.
- Replit Core — $25/month for full Agent access and $25 worth of credits (about 100 Agent checkpoints). The plan also includes unlimited public and private apps, access to Claude Sonnet 3.7 and OpenAI GPT-4o, deployment, hosting, and more.
- Teams (all Core features, $40 credits, guest access for up to 50 users, centralized billing, role-based access control, private deployments, and more) — $40 per month per user.
- Enterprise (all Teams capabilities, SSO/SAML, SCIM, guest access settings, advanced privacy options, custom pricing, priority support) — pricing is tailored individually and provided upon request.
Real-Time Collaboration and Teamwork Features
Replit is more than just an AI-enhanced code editor in the cloud. It's a collaborative coding platform that allows developers and other stakeholders to co-create apps and websites from prototype to deployment.
Opportunities for teamwork:
- The platform provides a collaborative coding environment. Several developers or teams can work on projects simultaneously. The platform supports real-time code editing and synchronously displays its execution for all participants.
- With the Join Link option, project creators can invite new participants by sending them unique private links. By clicking on such a link in Replit App, the user gets the ability to view and edit the code through the IDE.
- The link can be made public, allowing open access to modify the project’s code.
- Replit's real-time code collaboration features go beyond shared editing, offering tools for communication, version control, and synchronized development. Developers can discuss project details in built-in threads, review their colleagues' changes, and see files that have been added. There's also real-time Shell and Console I/O.
- The Replit Teams plan provides advanced capabilities for team collaboration. Its subscribers can develop and deploy custom teamwork tools, quickly prototype, publish team-wide templates and add-ons, branch/merge, and version control projects.
- The Repl Auth feature simplifies and speeds up the user authentication process, eliminating the need for developers to spend time creating and managing a separate database.
AI-Powered Coding Assistance and Productivity Tools

Replit AI coding assistant called Agent is the key tool of the platform. The developers presented the first version of the product in September 2024. In February 2025, it was updated to Agent v2, which received greater autonomy.
Functional features of the Replit AI assistant:
- Agent comprehensively automates the software development process. A user with no coding skills can manage all stages of development using text prompts.
- Experienced programmers can free themselves from routine tasks by entrusting them to artificial intelligence algorithms.
- In addition to generating code in more than 50 programming languages, Replit online code editor automatically performs a number of other operations. It edits code, configures the development environment and infrastructure, and analyzes large code bases, considering the context. Moreover, the assistant searches for necessary files and provides recommendations for the next stages of the project.
- Agent can adapt its methods based on user feedback and new instructions.
- The design and functionality of apps and websites are shown as real-time previews. This allows you to easily and quickly visualize various ideas and concepts.
- Agent can assist with the development of various types of applications. With it, you can make business applications, games, AI chatbots, medical and fitness trackers. It also helps to create online stores, blogs, marketing platforms, sites for selling online courses, and more.
In addition to the Agent intelligent assistant, the cloud-based IDE has a number of other features. They are aimed at increasing productivity and simplifying the daily work of developers:
- Developers can write code, collaborate, and deploy projects directly to the cloud. Work from PCs and mobile devices is supported.
- The template system allows you to save libraries and frameworks in different languages. They are convenient for quickly launching new projects. Importing code repositories from GitHub are available.
- Object storage allows secure storage of application data, accessible via a web interface. There is a dedicated secure storage for confidential data, such as passwords and API keys.
- Each registered user or team receives access to a fully managed PostgreSQL database with 10 GB of storage.
- Replit offers professional deployment and hosting tools for different types of projects. These include dynamic servers with reserved virtual machines, 99.9% uptime, and automatically scaling infrastructure. Real-time analytics, integration with Google Cloud services, and support for custom domains are also available.
