Inside your app
An in-app agent for selected tasks, using the application’s services and access rules.
Xangle / Custom software development
Custom software development.
We’re a team of developers building web, desktop, mobile, and Shopify applications. Start a new project with us, or bring us the software you already have.
New projects
Build the app you wish existed.
You’ve spent years adapting to software built for everyone else. We use coding agents and modern development tools to move quickly from your idea to a working application.
Custom interfaces, considered design, and a built-in agent that can act on your behalf.
Tell us what you’re buildingExisting applications
Modernize your old crappy apps.
Keep the business logic that works. Redesign the interface, improve the code, and connect your application to the services it needs.
Focused improvements can ship in days or weeks, depending on the code, integrations, and scope.
Show us what you have01 / Application modernization
Keep what works.
Change what gets in the way.
Your software has history.
Its interface doesn’t have to.
Keep the business logic people depend on. Rework the screens, code, and connections that make the application difficult to use or maintain.
Discuss your existing applicationA focused first release
- Understand the application
Identify the rules, data, and integrations that must survive the change.
- Redesign the useful parts
Simplify real tasks. Decide what to retain, refactor, or replace.
- Make the release explicit
Agree on what ships, how it is tested, and what any migration involves.
Focused projects can take days or weeks. A redesigned interface, a first working release, and a full production migration have different scopes and timelines.
02 / Agentic application development
Build new. Or add to what you have.
An agent that can
use the application.
Let people request information and carry out supported actions in the product itself.
We build the interface, application services, and tools behind the agent. Permissions and approval boundaries are part of the design, not an afterthought.
01 / Request
“Prepare this update.”
Intent becomes a supported action.02 / Review
See the proposed change.
Ask for approval where required.03 / Act
Call the application.
Use tools within the user’s access.04 / Confirm
Show what changed.
Return a visible result or an error.Through an MCP server
Model Context Protocol (MCP) connects compatible external assistants to selected information and actions.
Through a documented API
Full API documentation for the agreed capabilities: authentication, endpoints, formats, examples, and errors.
We agree on the supported actions and clients, required approvals, testing, deployment, operating costs, and maintenance before release. Modernization does not require an agent.
03 / Software we build and maintain

A practical place to start
Define the first useful release.
- 01
Show us the task
Who uses the software? What gets in their way? Start with a public link or a short description.
- 02
Set the boundaries
Identify the existing behavior, integrations, access rules, and constraints the release must respect.
- 03
Agree on the delivery
Define the scope, acceptance checks, deployment needs, and next steps before committing to a schedule.
Let’s talk about your software
Show us your app.
Or the idea for one.
Tell us who it is for, what you want to improve, and any timing constraints. We can start the conversation without repository access or confidential source code.
Xangle builds software and the systems around it.
