MastraI've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.
Based on our record, StackBlitz seems to be a lot more popular than Mastra. While we know about 112 links to StackBlitz, we've tracked only 5 mentions of Mastra.

Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 6 months ago
I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 8 months ago
I like htmx, LiveView, React and Solid. They are great at different points, and this is a prototype trying to combine them. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is added to achieve efficient DOM updates + minimal payload size.... - Source: Hacker News / 9 months ago
In the code editor tab (powered by StackBlitz), navigate to the env.ts file and enter your OpenAI key. Run npm run generate in the terminal to see how @autoview generates TypeScript frontend code from example schemas derived from both TypeScript types and OpenAPI documents. - Source: dev.to / over 1 year ago

Feature-wise, I feel Welt and welt-io both cover what they need to now. So the next step is growing the adapter lineup, and the current front-runner is Mastra (Strands' TypeScript SDK is also a candidate). - Source: dev.to / 8 days ago
The interesting frameworks for agents in TypeScript right now are Vercel AI SDK, LangChain.js, and Mastra. Each one gives you a tool-calling loop where the model picks an action, you execute it, and the result feeds back. None of them give you a tamper-evident record of what the agent actually did. - Source: dev.to / 3 months ago
I got tired of that blank moment. So I built DevNotion โ a 3-agent pipeline powered by Mastra that harvests my entire week of GitHub activity, narrates it into a first-person blog post using Gemini, and publishes it to Notion (as a planner-style page with structured tables) and DEV.to (as a draft article). Every Sunday, automatically, via GitHub Actions. - Source: dev.to / 4 months ago

I stood up a Mastra workflow via Telegram, pointed it at my three Cloudflare Workers sites, and ran it. Within five minutes it flagged scriptThrewException errors on all three sites. Bots were hitting my media proxy endpoint, the Worker was crashing on every request, and my uptime monitor had been saying everything was fine for days. - Source: dev.to / 4 months ago
