Fri, Jan 23, 2026Building a Private Bookmark Manager and Browser Extension in Replit [webinar]
Summary Replit hosted a livestream build session showing how to create a private bookmark manager with a Chrome extension from scratch using Replit Agent in under two hours. The team demonstrated how to write effective prompts, troubleshoot issues, and add AI-powered features like content summarization using OpenAI integration with minimal manual coding. Building the initial functional app and extension cost around five dollars using Replit Agent, with additional costs for feature iterations and enhancements throughout the session. The livestream showcased real-world debugging and problem-solving, including handling database migrations, security vulnerabilities, and browser extension authentication flows as they occurred. The start of 2026 is proving to be an exciting time for builders on Replit. In a recent livestream, community managers Manny Bernable and Raymmnar walked over 1,000 viewers through building a complete bookmark management application with a Chrome extension—live and unscripted—using Replit Agent.

Tue, Apr 22, 2025Secure Vibe Coding: The Tools and Fundamentals to Vibe Code Securely
Nothing is more exciting than realizing your vision. Nothing is worse than realizing you had a major security flaw. The good news? While security is crucial, it doesn't have to be an obstacle, especially when you're building on Replit. We integrate many security features directly into the platform, and our AI tools can handle much of the heavy lifting, letting you focus on building. This post is your practical guide to navigating security essentials. We'll walk through the key fundamentals to secure vibe coding, provide a security checklis, and give 16 practical tips for how you can vibe code more secure apps (and how to do so simply). Replit's five fundamentals for secure vibe coding Up to 40% of AI suggestions may contain vulnerabilities. At Replit, we've taken a unique approach: making security automatic and integrated for the most secure vibe coding possible.
Wed, Mar 26, 2025Secure Vibe Coding Made Simple
As vibe coding revolutionizes app development, security can't be an afterthought—it needs to be a core part of the creation process. Recent Stanford research shows that developers using AI assistants wrote less secure code in 80% of tasks compared to those coding manually, while being 3.5 times more likely to overestimate their code's security. And that's professional developers, we've seen an even more concerning trend among vibe coded apps. At Replit, we don't just take this seriously, we build security into every app you create with Agent, by default—something Replit CEO Amjad Masad has called "the Pit of Success". That's why our apps are secure, by default. We bake security in to the process of building with Agent—so you can focus on creating.
Wed, Mar 26, 2025What is Vibe Coding?
From idea to app, fast—that's always been our mission at Replit. But what if you could turn your ideas into working apps without knowing how to code at all? Enter vibe coding: a term that's democratizing app creation for everyone, regardless of technical background. What is vibe coding? Vibe coding refers to the practice of instructing AI agents to write code based on natural language prompts. It's not about being lazy—it's about focusing your time and energy on the creative aspects of app development rather than getting stuck in technical details.

Sat, Mar 8, 2025Everything you need to know about MCP
You can find the 3-min quickstart from the video here What is MCP? MCP (Model Context Protocol) is a standard way to connect AI models to data sources and tools. It allows AI to access information and capabilities beyond what they were originally trained on. MCP works like a universal connector for AI systems. Just as standard ports let different devices work together, MCP lets different AI models connect to the same tools and data sources. This means developers can build a tool once and have it work with any AI model that supports MCP. It's like the USB-C port of AI applications.

Thu, Jan 16, 2025AI Coding is Better with Python
"Can everyone really code with AI?" I hear this question all the time. Usually after someone sees a viral post about an AI-built app and thinks "I could do that too!" But here's what those posts don't tell you: most AI-generated apps are just pretty shells—nice looking websites that lack functionality. Why? Most AI coding assistants build with JavaScript and are optimized for presenting information to the user (frontend development). These apps lack the backends and services that power functional applications. JavaScript is great. It creates beautiful frontends—Replit’s AI tools use it well. But Replit is unique: we don’t only use JavaScript. In fact, there are many times it’s not the right tool for the job. Perhaps you’re:
Tue, Dec 10, 2024Announcing the New Replit Assistant

We’ve helped millions of people learn to code and made programming less intimidating. But now, thanks to our Agent and Assistant, our AI coding products, we’re taking a giant leap forward. You don’t need to learn coding to be a creator — you just need an idea. From local realtors in Cleveland to Japanese influencers to product managers at some of the world’s largest enterprises, people are building incredible things on Replit. We no longer need to limit ourselves to being users of software, we can all be creators. Today, we’re taking Replit Agent out of early access and officially launching it with groundbreaking updates that will radically expand who can create software. Let us show you what’s possible.
Tue, Oct 8, 2024From localhost to live
If you have a body, you are an athlete. Bill Bowerman, Co-founder, Nike The title "programmer" was always reserved for those who code. So it make sense that shipping software is synonymous with, well... writing code. But is the hardest part about shipping really learning to code? I wish. The hardest part(s) are everything that lives between localhost and live. Today, we're seeing a new class of builders—the AI native developer. These users have some technical prowess and build through clever use of the latest tools. But the problem was never just writing code. Despite lower friction to code, roadblocks still exist. Where, you ask?
Mon, Sep 16, 2024Introducing Replit Agent
Last week, we launched Replit Agent, our AI system that can create and deploy applications. Now, with only a few sentences and a few minutes, you can take an application from idea to deployment. You can think about the Agent like a pair programmer. It configures your development environment, installs dependencies, and executes code. From your laptop or the Replit mobile app, the Agent is changing how our users build software. If you'd like to learn more, we've compiled some of our favorite examples, tutorials, and articles on the agent so far.
Wed, Aug 14, 2024How Replit makes sense of code at scale
Data privacy and data security is one of the most stringent constraints in the design of our information architecture. As already mentioned in past blog posts, we only use public Repls for analytics and AI training: any user code that's not public — including all enterprise accounts — is not reviewed. And even for public Repls, when training and running analyses, all user code is anonymized, and all PII removed. For any company making creative tools, being able to tell what its most engaged users are building on the platform is critical. When the bound of what’s possible to create is effectively limitless, like with code, sophisticated data is needed to answer this deceivingly simple question. For this reason, at Replit we built an infrastructure that leverages some of the richest coding data in the industry. Replit data is unique. We store over 300 million software repositories, in the same ballpark of the world’s largest coding hosts like GitHub and Bitbucket. We have a deeply granular understanding of the timeline of each project, thanks to a protocol called Operational Transformation (OT), and to the execution data logged when developers run their programs. The timeline is also enriched with error stack traces and LSP diagnostic logs, so we have debugging trajectories. On top of all that, we also have data describing the developing environment of each project and deployment data of their production systems. It’s the world’s most complete representation of how software is made, at a massive scale, and constitutes a core strategic advantage. Knowing what our users are interested in creating allows us to offer them focused tools that make their lives easier. We can streamline certain frameworks or apps. Knowing, for instance, that many of our users are comfortable with relational databases persuaded us to improve our Postgres offering; knowing that a significant portion of our most advanced users are building API wrappers pushed us to develop Replit ModelFarm. We can also discover untapped potential in certain external integrations with third-party tools, like with LLM providers. It informs our growth and sales strategy while supporting our anti-abuse efforts. And, of course, it allows us to train powerful AI models. Ultimately, this data provides us with a strong feedback loop to better serve our customers and help them write and deploy software as fast as possible. While all this is true, it’s also not an easy feat. Several challenges come with making the best use of this dataset, and all stem from the astronomical magnitude of the data. We store on Google Cloud Storage several petabytes of code alone, and our users edit on average 70 million files each day, writing to disk more than 1PiB of data each month. This doesn’t even consider OT data, and execution logs, both in the same ballpark for space taken and update frequency. Going from this gargantuan amount of raw programming files to answering the question “What is being built?”, all while being mindful of user privacy, is, well, hard.
