Building RSC Boundary this week made me want something specific from Next.js: An extension surface for the dev indicator. Right now, the little Next.js logo in the corner is great for what it does. Routes, errors, build status. But it's closed. Any tool that wants to surface additional dev feedback has to ship its own floating UI and hope it doesn't clash with yours. RSC Boundary does exactly that. It works, but it feels like the wrong layer. If the dev indicator had a simple plugin API, tools like this could live right where developers already look.

@LisaLi_T @tokifyi Is the win required? 😅

Hosting the first Builders & Skewers series meetup w/ @tokifyi next week! 🥳 No agenda, just great food and a way to meet interesting founders across domains and to celebrate our wins together. We're only reserving a small table, so RSVP if you want to make it!! luma.com/ljhx10i8

In 2026, • Every idea feels taken • Every API already exists • Every SaaS has 12 competitors • Every startup is already on Product Hunt So what the hell do we build now 😭

@tokifyi @vancouverdev_ Hell yeah, Breka is too crowded 😅

@valentinprgnd @vancouverdev_ nothing planned for now maybe once we launch the builder cafe, it’ll be an event space too

in the last 48 hours: > started 10fold.ai → already got a bunch of meetings booked > joked about doing an ai retreat in tofino → now it’s probably happening, details coming soon > been talking to people about building vancouver’s first 24/7 automated cafe for builders you really can just do things

@tokifyi @vancouverdev_ Not yet. Any events coming up?

@valentinprgnd curious have you been to any of the @vancouverdev_ events?

@tokifyi I’m down!

this is cool i’d love to do something like this in vancouver, a 24/7 cafe for builders anyone interested?

@tokifyi Cobra chickens! 😅

actual footage of me and our forward deployed engineers showing up at canadian businesses to make them ai-native

@tokifyi @LisaLi_T That spot looks great 😎

@SammyTourani Still a work in progress, but here it is! aftermath.sh

If you're a founder, builder, vibe coder, head of growth, researcher, or simply just working at a startup, let's connect!

@faizan10114 😅

@valentinprgnd meanwhile montreal.

Always Toronto, Vancouver startups, reveal yourselves! 👀

@ilyabrotzky 👀

@valentinprgnd Vanna.com can help

@dubeyansh_ @BMO Not yet, I barely browsed their website 😅 But the unlimited interac transfers and multi-currency on the free tier seemed worth it

@valentinprgnd @BMO Was just about to look at them. And I totally agree, they do look good. Do you know how well they support sole props?

What’s the best bank for a sole prop in Canada? Signed up for @BMO and their online banking portal is brutal. I just need the Wealthsimple equivalent for a small business: clean UI, simple transfers, and no 2005-era banking experience.

@haydenbleasel That video is clean, what tools did you use? 🧐

Files SDK 1.4 → 9 new storage adapters → new CLI for agents → installable skill → optional peer deps

@fortysevenfx Wanna run it on github.com/foxted/rsc-bou…?

If you publish NPM packages from GitHub Actions, send me your repository link, I'd like to eval my audit skill on it. DMs are open.

@maxktz @Cloudflare Tried sending a bunch of events with ab in the terminal, some event were not forwarded locally

@valentinprgnd @Cloudflare what do you mean by event dropoff? maybe i can help

webhook relay powered by @Cloudflare btw it's free, so I hope my infra bill won't be too big😅

@maxktz @Cloudflare Thanks! The main issue I keep running into is event dropoff, tried to let the CLI throttle itself, but I am still losing events fron time to time 😅

@maxktz @Cloudflare Interesting solution, decided to go with gRPC with Hookie (still work in progress): hookie.sh

@RhysSullivan I like this install pattern: `npx executor web`, it’s convenient!

I'm now building Executor full time as a startup! The state of tool calling is a mess: - Everyone is using different agents - You have no idea what actions are going to run - Destructive actions are treated the same as normal Executor lets you set up everything once & use it with any agent. You're able to control what tools can be called, require approval on destructive actions, and invite your team to all use them. Under the hood, it's built on codemode to let you add thousands of tools with 0 context bloat. I've been using it for a month so far and it has completely changed how I interact with agents. There's so much to be built here, immediately next up on the roadmap is workspaces, skills, workflows, and generative ui. Everything is being built open source over at github.com/RhysSullivan/e…, there's a lot more coming on an SDK to embed it into your own agents, a self hostable cloud app, and plugins There's an early beta version over at executor.sh. It's very early on - if you hit any bugs let me know and I'll get them fixed up, excited to share more as I build it!
