Say it in plain words and it gets built. Apps, sites, mail, tasks, and the AI agents that keep them all moving.
Say it in plain words
Tell OpenKBS what you need, the way you'd explain it to a coworker. It writes the code and shows you a working app while you wait.
Change it until it's right
Point at what's off and say what you want instead. OpenKBS makes the change and puts the new version live. Nothing waits for a release date.
Integrate and schedule
Connect your inbox and the tools your team already uses. Set agents to run on a schedule, so work happens without you: sorting the inbox, chasing invoices.
What our customers say
“We came with an enormous specification — thousands of requirements — and it absorbed all of it without losing the thread. What comes out is a real system, not a pretty prototype.”
“The platform has tools for literally everything I needed, all in one place. Whenever I hit a difficulty, I got a quick response and practical advice.”
“The most advanced vibe coding platform I have ever used. It takes the task, discusses it and makes a roadmap — acting as both programmer and project manager.”
“Even people with little to no technical background can quickly create beautiful, smart and highly functional solutions in a very short time.”
“I build and host AI agents vital for our business performance, turning manual work into automated processes. Adding new features is simple with a single prompt.”
“All I need while working is in one place, with great UX.”
More than an AI app builder
Most companies run on a pile of separate tools that talk to each other via wonky connectors. OpenKBS puts all of it in one place, under one login and AI brain.
Apps and websites
Real software your staff and your customers can use, live on the internet, with a real database behind it.
Your domain and email
Your web address and your mailboxes, set up inside the project. Your agents can read and send mail from them.
A board for the work
Everything your team is working on, in one shared list. Agents add to it and take work from it.
Your team
Invite whoever needs to be there. You decide what each person and each agent is allowed to touch.
AI agents and routines
They read mail, update records, move tasks and start jobs. Put them on a schedule and they work while you sleep.
Frequently
asked questions
What is an AI app builder?
It's a tool that builds working software from a plain-language description. With OpenKBS you describe the app, website or AI agent you need, and it writes the code, sets up the database and puts it live.
Can I build AI agents for my business?
Yes. AI agents live in the same project as your apps, mail and data, so they can read the inbox, update records and move tasks on the board. You decide what each agent can touch, and you can run it on a schedule.
Do I need to know how to code?
No. You describe what you want and point at what to change. Developers can also work on the code directly through the OpenKBS CLI.
How much does it cost?
You can start free with one project for testing and demos. Paid plans start at €19 a month, excluding VAT, and include credits that pay for the AI, hosting, database and mail. See pricing
Can you build it for us?
Yes. Our team builds custom software with you on the same platform, trains your people to run it and stays on for whatever comes next. AI development services
