Independent software studio · Europe

Small software.
Built properly.

Sidelobe builds custom web apps, internal tools and automation. If your team spends too much time updating spreadsheets, chasing approvals or moving data between systems, there may be a simpler way to do it.

What Sidelobe builds

A shared dashboard, an approval flow or a connection between two systems. The scope depends on the work your team needs to do.

01

Internal tools

Manage requests, records and approvals in one place.

 02

Workflow automation

Sync data, send reminders and connect the tools you already use.

 03

Custom web applications

Build portals, planning tools and apps for staff or customers.
04

Prototypes

Try out an idea with a working app before committing to a full build.

Typical starting points Where the manual work adds up.
  • the same information is entered in several places
  • requests get lost between email and chat
  • a spreadsheet has become difficult to manage

Open-source projects

OSS / 001

RuntimeTruth

A CLI that compares Codex runtime state with a reviewed baseline. Check for changes in model settings, instructions, permissions and MCP tools.

OSS / 002

PowerContract

Define signal mappings, voltage limits and timing checks in YAML. Run them against waveform CSV files and review the results.

GitHub

Browse the repositories

Read the source, try the examples or report an issue. Development and release notes are available on GitHub.

How a project runs

Agree what the software needs to do, review working versions during the build and plan how it will be deployed and maintained.

  1. 01 / scope

    Define the first version

    Walk through the current process, identify the users and agree the scope, constraints and priorities.

    An agreed scope
  2. 02 / build

    Review working software

    Try the main screens and workflow early. Feedback goes into the next iteration while changes are still straightforward.

    A working version to test
  3. 03 / ship

    Prepare for everyday use

    Set up deployment, access and monitoring, then document how to run and maintain the application.

    Deployment and handover
Do I need a specification?

No. Describe the task, who does it and what takes too much time. Requirements can be worked out together.

Can an app work with tools we already use?

Often, yes. That depends on the APIs, exports and permissions available. These are checked before agreeing the integration work.

Can we start with a small version?

Yes. Start with one useful workflow, test it in day-to-day use and decide what to add next.

Is Sidelobe only for internal tools?

Sidelobe also builds customer-facing web apps, prototypes and automation.

What would you like to build?

Describe the problem, the people who would use the app and any tools it needs to work with.
