A free web database for building business systems without code
Exment is a free, open-source (GPL) web database. Just define the fields you want to manage on screen, and you can build a system that fits your business: customer management, deal tracking, requests and approvals, and more. Because it runs on your own server or in the cloud, you keep your data in-house. And pricing never grows with the number of users.
Free, unlimited users
Completely free when installed on your own server. No limits on users or features, so costs stay the same as your team grows.
No-code configuration
Set up tables and fields on screen. The core features are rich, yet simple and easy to understand.
Get started with templates
Business templates such as Task Management and Customer Management are ready to use.
Extend with plugins
Add features unique to your company, or generate documents in your usual Excel format.
Connected data, less searching
Link many kinds of data, such as customers, contracts and maintenance, and manage them on a single site.
Runs on your server, so you own your data
Install it on Windows, Mac or Linux, on shared hosting (such as XServer or Sakura Internet), or in the cloud (such as AWS or Azure).
Concept
Exment is "a web system that can manage anything." Start by watching the concept video.
As you add the things you want to manage, Exment can take on many roles. Set it up for customer management and it becomes a CRM; set it up for task management and it becomes a task tracker. System administrators can configure it freely, so the possibilities are endless.

Manage in lists
Example: inquiry management. Status and priority are shown as colored labels.

Move tasks forward
Example: task management. Drag cards across the Kanban board to make progress.

Run requests and approvals
Example: approval requests. Manage the approval flow with workflow.
* Screens are from Exment 7.0. For 7.0's new features (Kanban, Gantt charts and more), see What's new.
Thinking of leaving a per-user priced service?
With cloud services that charge per user, costs rise as more people use them. Exment is a good fit for companies that want to keep costs down:
- No license fee (GPL). The commercial license is also priced per site, not per user (Pricing and support).
- Keep your data in-house. Choose where it lives: your own server, shared hosting or the cloud.
- Take your time before deciding. There is no trial time limit. Test it on your own PC or in a demo environment for as long as you need.
- We can help you migrate. Our onboarding support (table setup and data migration) can move your existing Excel or spreadsheet data. Ask us about migrating from other systems, too.
A tool to move app definitions and data from other services in one go is on our roadmap.
Benefits of Exment
Rich core features
We often hear comments like these from our users:
- "The core features alone are more than enough."
- "Search is easy to use, and showing related data in a list is especially handy."
- "It's simple, so anyone can use it after a quick explanation."
The screen on the right shows the results of a search for "Japanese cuisine." All customer information related to Japanese cuisine appears together in one list.
Ready-made business templates
We provide templates for specific tasks, such as Task Management and Customer Management. With a template, you can start working right away without building everything from scratch.
We will keep adding more templates. If there is a template you would like to see, let us know through our contact form.
Link many kinds of data on one site
When customers, contracts and maintenance live in separate systems, handling a single inquiry can take steps like these:
- Look up the customer in the CRM
- Check the same customer again in a separate contract management system
- Record what you did in the maintenance system
With Exment, customer, contract and maintenance information is linked and managed on one site. When an inquiry comes in, you can find what you need right away.
Free to use
Exment is open-source software. If you install it on your own server yourself, it is completely free, with no limits on users or features.
Add features for your business
Freely add features that fit your company's unique processes. Create documents such as quotes and invoices on screen, using the Excel files you already have. How to add features is documented in the manual, so developers can build their own.
Try it thoroughly before adopting
Typical services give you only a limited trial period. Because Exment is free, you can test it on your own PC as long as you like, then install it on your server or use our cloud service.
