🧪 the next layer after AI coding is AI testing.
if AI can help create more software, AI also needs to help verify that software.
toolbar is building that layer for web apps.
a testing agent that can create browser tests, maintain them, run them after changes, and show teams what actually broke.
> real devs buy a toolbar sub so their product doesn’t break.
Developers, if you have $2K.

a broken signup flow is not just a bug.
> it is lost pipeline.
a broken billing flow is not just a bug.
> it is lost revenue.
a broken onboarding flow is not just a bug.
> it is lost activation.
toolbar helps teams monitor and test the flows that directly affect the business.
nnot just whether the app loads.
whether the important journeys still work.
the scary part of shipping is not the deploy.
it’s not knowing what broke.
most teams don’t find regressions because they are impossible to catch. they find them late because nobody checked the right flow at the right time.
toolbar runs your critical browser flows before changes reach customers.
> signup.
> login.
> onboarding.
> billing.
> checkout.
> dashboards.

toolbar weekend recap:
6 companies want to implement toolbar.
with half of them we’re already working closely to make sure it works the way they need
since I just became unemployed,
we’re launching vibe testing at toolbar.
an agent backed by a full testing infrastructure
that tests your product after every update
so nothing quietly breaks while you keep shipping.
under the hood,
it’s a self-updating e2e test suite that generates, heals, and expands itself as your product changes.
every new update triggers a fresh run,
so your tests stay aligned with the real product
instead of slowly becoming useless.
100 followers on x.
not 100k.
not viral.
not “we broke the internet”.
just 100 real people watching us build toolbar.
small number, big vibes.
thanks for being early!
I cost that much...?
running a startup is funny because the costs are never just “hosting and a domain.”
right now, our stack looks something like this:
figma, $40/mo
codex, $200/mo + cursor, $20/mo
x premium, $5/mo
amie for meetings, $25/mo
ai api costs everywhere
infra around $200/mo each just to get started
and then a bunch of personal expenses on top of that.
startup life is mostly just turning subscriptions into product.
