I gave the same prompt to Lovable and Flowdia — build a video transcoding platform with FFmpeg, HLS streaming, audio extraction, and GIF export. Lovable said "I'll build the UI, you handle the backend." Flowdia just built it. Same prompt. One ships a mockup. The other ships a working app. That's the difference between controlling the code and controlling the runtime.

This might be the second open source tool fully built with Grok build :D While it's still in beta, both grok build and pg_rolequota extension, you can give it a try, I'm testing it locally myself, and will keep pushing fixes and updates. Let me know what you think: github.com/flowdiahq/pg_r…

Very cool - Grok Build is clearly getting better by the day. Two nights ago I ran an overnight build and it failed. Last night, success. I really like the multi-agent orchestration behavior, it does a really good job of spinning up agents to build vs. review, and an orchestration agent that makes sure everyone follows the plan. I'm impressed, the @xai team is clearly making really meaningful progress here, very quickly.

Grok Build continues to amaze me! I wanted to build a real, production-grade PostgreSQL extension. The goal was per-role disk quotas with soft/hard limits, two different scanning strategies (one cheap, one authoritative), background workers that spawn dynamically per database, a low-latency wakeup mechanism, mid-query cancellation, and strict safety around shared memory and locks. All while following extremely rigorous rules around testing, code style, and correctness. This is deep systems work: custom shared memory structures with EXEC_BACKEND safety, hook chaining, careful latch and transaction management in background workers, and hazard contracts that are easy to violate. What impressed me most was how well it handled the complexity. Grok didn’t just generate code, it researched PostgreSQL internals, helped design the architecture, caught subtle bugs, it actually started real PostgreSQL instances, reproduced crashes (including a nasty background worker segfault), diagnosed the root cause, and fixed it. The result is a fully working extension with proper multi-database support, real enforcement, and comprehensive tests. Here’s the extension running in practice: Grok Build is genuinely strong at serious, low-level systems programming. I think I'm in love! Repo coming soon. #PostgreSQL #Grok #xAI

This is GOLD, Grok build just spawned 3 different reviewers agents each for a specific area of review I asked for, then gathering all findings under 1 review file for the implementer to fix and work on! seriously, If this is the beta, then what will the first release will look like! I can't really find differences between Grok Build, Claude code or codex, currently Grok build is on autonomous mode building a postgres extension I need for Flowdia, let's see how it will do!

@morganlinton Got this yesterday after it built a UI for me

Talk to Grok Build is like talking to a friend 🤝

The more we say convex is a backend stack, and Auth is separate from Backend, the more Engineering is fading in the shadows! If you do not own every single line of code in your codebase, you will regret it on the long run.

I have been living in the terminal for the last 11 years, vim + tmux everyday, and I can say that Grok Build feels so native to the terminal than any other CLI Agent.

@morganlinton cross platform clipboard sharing ? that's the only teaser in the screenshot 😅

Okay, got the greenlight from Grok Build, I think I'm ready to launch my first piece of software, open source of course, built with Grok Build. And common, gotta love it's enthusiasm, I feel like Grok is just as excited as I am 🔥

Ok, Grok build is much faster than claude or codex, it also follows instruction waaaaaaay better

@morganlinton the best TUI at this point!

Grok Build's plan mode, in the TUI, is the best I've ever seen for an agentic coding CLI, so good 🤌

@victor_bigfield landing page video, 1000 visitors, and not a single one played it 😅

real question for indie founders here: what's the dumbest thing you optimized for weeks that never moved a single metric? i'll start: hero of the landing page.

@KaiXCreator Only if someone hit me on my head with this solid reason

Give me one solid reason.. to choose a Windows laptop over a MacBook

Grok Build didn't fully fix the problem, but it helped really well, it contributed 50-50 to the fix along with claude, man it's so good, and I can't help moving my eye away from it's beauty, I think I'm in love

Just purchased Grok Build heavy plan, giving it a try on a complex problem I have, that neither codex or claude solved

Grok Build is hands down the most beautiful TUI at this point!

multi-agent BMAD (not bhappy :D) pipeline in elixir. analyst, pm, ux, architect, scrum master, dev, qa. each agent is its own phoenix process with its own system prompt, tool allowlist, and memory artifacts. handoffs through redis-sqlite-backed memory & Knowledge graph so each agent only sees what it needs. dev doesnt see business framing, qa only sees the spec plus the diff. models routed per-agent. tool-call loop runs in gvisor containers against a per-app mcp server we proxy through. hardest part was role boundaries. early version had the pm agent rewriting code because it had tool access. fixed by stripping tools per role. agents only get what their role needs.

@islamtaha how did you build them?

i'm working on some sdk design for v2 what i keep coming back to is not fully understanding one segment of the usecase every infra company is prepping for "millions of agents to run on us" are you working on a product that needs this? tell me more

Try not to ask Claude/ChatGPT for an opinion on posts before posting. Just do it. What is the worst that can happen?

@Tech_girlll When they have 100+ on the Engineering team

Let’s end the debate: when is the best time for a company to switch to a microservices architecture?
