Mainframe

i'm getting tired of reading prs... so i hacked @cursor_ai cloud agents to narrate the demos they send me. now all i have to do is watch a video :-) bonus: it's my own voice so i can send these to teammates or customers turns out all you need is a prompt! (see next tweet)

nyc @mainframe office day one

at @mainframe our agent has a special command that spins up an isolated, local convex deployment and frontend. convex is normally 1 cloud deployment per developer. but this lets us spin up dozens of cloud agents and worktrees at once. we also have agent-only ui, like sign in!

agents never get tired, yet we make them go to bed when we do. 2026 will be the year we tell them it's ok to stay up: the year of overnight agents. e.g. this morning we woke up to a pr from @async. if you get a good pm and @cursor_ai bug bot, shipping no longer has to stop.

we recently had a database bandwidth spike our AI PM @async followed up to make sure it was fixed

bring your plans from @async into any coding agent like @conductor_build with the build button

idk if he enjoys it but i send my pm voice notes when i’m on walks. by the time i’m home he’s implemented it together with eng.

vibe planning — just send async a voice memo

plans ui for @async

good pms write, great pms prototype. async can now use @v0

jordan and team really, really care about this problem. it's clear in their responsiveness and level of craft. if you ever feel like you're spending half your time trying to remember what you need to do instead of actually doing it, you need to check out async

I’ve seen early demos of Async. It’s a bold shift in how teams choose what to build and prioritize from a pre-AI era. Love this direction.

i’ve worked three roles throughout my career: designer, design engineer, engineer. regardless of title, the hardest part was always the same: figuring out what to build and why, and aligning with humans. yet we have coding & design agents, but no product agents. meet @async

we're excited to share @async and the "product agent" for the first time:

rolling out a new @mainframe exploration to the first customer today

One of the most original website designs I have seen from a while is from @jsngr and his company @mainframe really clever and nostalgic.

As of today, we’re announcing that we’re winding Cobot down to focus on what’s next. blog.mainfra.me/p/sunset

we're exploring something @mainframe to help small teams. if you're at a <10 person company and down to chat with @jsngr and i about how you work... let me know :) you'll get our eternal gratitude and beta access down the road.
