You can now use Convex with a single command without needing to set up a Convex account. This means it’s even easier to persuade your friends to check out Convex and to share an app that others can download and run for themselves.
Agents rely on long-lived workflows, but when happens when they fail midway through? Here are the tools you need to manage correctness and reliability: transactions, idempotency, retries, durable functions, journaling, and state machines. The missing abstraction layer for agentic is durable workflows, which bring them all together.
With this new backend component, augment Agents to automatically save and search message history per-thread, providing realtime results across multiple tabs and users. Use it with the Workflow component to run reliably with retries and durability across server restarts.
Convex MCP Server is now generally available, enabling AI agents to query your data, run functions, and automate complex tasks. Here are two crafty use cases we've already uncovered...
AI coding is here: The most productive developers are leveraging AI to speed up their workflows. This ranges from asking models questions about system design to letting AI take the driver's seat with tools like Cursor Composer.

New convex-helpers are available now for fetching streams of documents, merging them together, filtering them them out, and paginating the results. With these helpers, you can replicate patterns you may know from SQL: UNION ALL, JOIN, DISTINCT, GROUP BY, and WHERE clauses where index fields are skipped.

Here’s a cheatsheet with examples of conversions between SQL queries and Convex queries. This article is geared towards developers (and LLMs) who have familiarity with SQL and want to translate those familiar patterns into Convex queries. You'll learn how to `UNION`, `JOIN`, `DISTINCT`, do `WHERE` clauses, and `SELECT` fields.

Convex might look like just a database, but for modern app developers, it's a full backend-as-a-service platform that replaces the complexity of stitching together ORMs, caching, rate limiting, realtime sync, and CI/CD. In this post, a startup founder walks through how they used Convex to build ClarityText—an AI-powered chat knowledge base—and explains why Convex delivers faster MVPs, deeper type safety, and a seamless developer experience without third-party services like Prisma, Redis, or Firebase. Perfect for developers evaluating backend choices in 2024 and beyond.

Convex Panel simplifies development by integrating Convex’s powerful dashboard directly into the dev environment, eliminating the need to switch between browser tabs. Built as a React component, it provides real-time logs, table editing, and performance insights seamlessly within your workflow. This tool enhances productivity, streamlines debugging, and optimizes backend management for developers using Convex.

Moving data between databases is never fun, but I needed to get 2 million MongoDB documents into Convex without losing my mind. This post walks through my migration script, covering everything from connecting databases to handling schema changes, batch processing, and error handling. If you’re thinking about moving from MongoDB to Convex, consider this your survival guide—coffee highly recommended!

Authentication issues in real-time applications can cause security risks, especially when client-side queries run before validation. Ensuring authentication at the server (Next.js middleware), client (useConvexAuth()), and database (Convex functions) helps prevent unauthorized access. Using middleware, enforcing authentication in Convex functions, and leveraging custom hooks improves security and performance.

Agents rely on long-lived workflows, but when happens when they fail midway through? Here are the tools you need to manage correctness and reliability: transactions, idempotency, retries, durable functions, journaling, and state machines. The missing abstraction layer for agentic is durable workflows, which bring them all together.
I reimplemented Mastra’s agentic workflows with durable functions in Convex, and it was the wrong decision. Look at three common strategies (reimplementation, API wrapping, and “blessed” plugin paths), along with learnings along the way and reflections on what I’d do differently next time. TL;DR: Do less, do it smarter, and prototype faster.
