The zero-setup cloud for small software
Everything your AI-built tools need. None of the setup.
Bring working code straight from your machine. Cohostly makes small tools usable with hosting, authentication, data, AI, OAuth integrations, and access controls—without stitching together a cloud stack.
No mandatory Git repository. No deployment config maze.See how it works
I. The part nobody wants to build
The code was the easy part.
Claude Code, Cursor or Codex can get a useful tool working in an afternoon. Then comes everything that makes it usable by someone else.
II. The usual way
You wanted to ship software. Not become its infrastructure team.
9 chores, hung out to dry. Again for every app.
III. From local to live
Works on your machine? Good. Start there.
i.
Build it your way
Claude Code, Cursor, Codex or your usual editor. Run it until it works.
ii.
Snapshot the folder
It packs the project as it is and works out the runtime, start command and port.
iii.
Deploy it
Check the settings, say yes, and get an app URL.
iv.
Add what it needs
Turn on sign-in, data, AI and integrations, then share it by email.
No terminal? Upload the folder, connect GitHub, or ask your assistant over MCP.
ONE COMMAND
Your folder, as it is.
platform deploy packs the project you already ran (leaving out node_modules and .git) and works out how to start it. You see the settings before anything goes live. Try it.
There is no manifest, so here are the settings worked out from your code.
Example settings. Yours come from your code, and you can edit them first.
IV. More than a place to host
Your app deserves more than a URL.
Built in, and built to work together: sign-in knows who is calling, connections use their consent, approvals ask the right owner.
i.Local deploys
From your folder, as it is.
ii.Sign-in
It knows who is calling.
iii.Saved data
A database for each app.
iv.AI built in
Models with no key in code.
v.Managed OAuth
Accounts linked once.
vi.Schedules
Runs while the app rests.
vii.Access
From public to private.
viii.Your OK first
Risky steps wait for a yes.
ix.No repo needed
Look after it by role.
x.Undo
Every version kept.
TWO · CONNECTED
Let your tools do more than sit in a browser tab.
Managed OAuth, AI bindings and schedules mean the integration work is done once, by the platform. Reading someone’s data and acting for them are separate permissions, and acting waits for a yes. Try it.
May I send this week’s summary to 6 people?
Sheets and Outlook are separate connections with separate permissions. The app never holds a token.
THREE · NO KEYS
Your users never bring an API key.
An AI resume editor, shared by link. People sign in and use it. Nobody clones the code or pastes a provider key, because the app calls models through Cohostly and you set the spending cap.
Tighten this bullet.
FOUR · ACCESS
Share the app. Not the repository.
Every app gets its own address. Pick who can open it. The app knows who each person is, and only sees a name or email if they agree. People who use it and people who look after it get different roles.
Who can open it?
People in your account can open it.
VI. The cloud, rethought for small software
Most clouds help you deploy. Cohostly helps your little apps work.
ROUTE A · THE USUAL WAY
Eight stops.
Rewired for every app.
ROUTE B · COHOSTLY
Four stops.
The same every time.
VII. Platform by platform
Every cloud can host code. Here’s what you set up yourself.
Each row is something a small app needs. Each box says how you get it on that platform.
DETAILS · TAP A ROW
Connect Google, Slack…
Tokens held, refreshed and scoped per person
Vercel Connect

Cohostly is shaped for many small tools. Big, high-traffic or multi-service systems may fit the others better. Read the long version
VIII. Made for the software you actually need
Not every useful app needs a million users.
i.AI resume editor
Friends open a link and get suggestions. No keys to paste.ai · context · link
ii.Small-team dashboard
Only your team can open it, and the numbers live in its own database.team visibility · data
iii.Automated reporting
Runs on a clock, reads a sheet, and waits for a yes before sending.cron · connections · approvals
iv.Personal workflow app
Private to you, its data kept and backed up. It rests when you do.private · data · backups
IX. For people who can’t stop building
A home for all the little things you make.
One useful tool becomes five. Five become twenty. A script that saves an hour. An internal dashboard. A weekend experiment. They all deserve a place to run—without becoming twenty separate infrastructure projects.
Keep making software. Spend less time maintaining its setup.
X. Questions
Asked, and answered plainly.
Small software. Less infrastructure drama.
You’ve already built it. Put it to work.
Bring your working code to Cohostly. Get it online, give it the capabilities it needs, and let people actually use it.
