Don't guess. Measure.

I am Ben Dangelmayr, a software developer in Heidelberg. I build free apps for Jira Cloud and custom web tools for small businesses at fixed prices.

10 free Jira apps on the Atlassian Marketplace · reply usually within 1 to 2 business days · How the products are built

Three of the apps in 15 seconds: External ID Guard finds duplicate references, Stale Radar finds forgotten issues, Automation Heartbeat finds silent automations.

Ready-made tools for your platform

Small, focused apps: install and go. Each app does exactly one thing. Its docs state what it reads, what it stores and where its limits are.

External ID Guard: INV-1001 on XGC-1 and XGC-2
External ID Guard in Jira Cloud, captured in a test project. Full-size capture

The same reference on two issues

External ID Guard flags duplicate values in a chosen text field. In the example, two issues carry the reference INV-1001. The app shows the finding and does not change any Jira data.

Apps for Jira Cloud

10 on the Atlassian Marketplace

All apps for Jira Straight to the Atlassian Marketplace

Why the apps are built this way

Platform-native, no egress
The apps process your Jira data inside the Atlassian infrastructure (Forge). No external servers, no AI services, no tracking. What an app reads, writes or stores is listed in its documentation. App privacy
Minimal permissions
Each app requests the permissions listed in its docs; nine of ten need no write access. What you see in the interface is read with your own permissions (asUser): only what you can see in Jira yourself becomes visible.
Documentation with limits
Every docs page states what the app reads, what it stores and where its limits are. All docs
Security with a reporting path
A public security policy with a disclosure path and security.txt. Vulnerability reports are welcome and handled with priority. Security policy

A tool for your business

If your workflow does not fit off-the-shelf software, I build the tool that does: in the browser or locally on your machine, at a fixed price agreed up front.

Web apps & digital tools

Your workflow, turned into software: calculators, admin tools and planning instead of paper piles and spreadsheet chaos. Runs in the browser, or fully local on your machine if you prefer.

  • Runs in the browser, nothing to install
  • Fully local on request: no cloud, no forced subscription
  • Tested logic, documented limits
from €1,400 For focused tools with one core job, for example "From Excel to a tool". Start a project

In the intro call we clarify the workflow, then you receive the quote. During development you see intermediate versions.

The person behind Dangel Studio

Dangel Studio is one person, not a faceless team. I build these products myself, and I work by one simple principle:

I build with AI support and test every result before handover.

Good to know

Answers to the most common questions about the apps and working together.

Is my Jira data sent to you or to third parties?

No. The apps run entirely on Atlassian Forge and send no Jira content to my servers or anyone else's: no tracking, no AI services. To do their job they process Jira data inside your own site, and some apps keep small configuration or history records in Forge storage there. What that is for each app is stated on its docs page and in the Atlassian apps privacy policy.

What do the Jira apps cost?

The current apps are free ("Commercial – no charge" on the Atlassian Marketplace). If paid versions come later, billing will run entirely through the Marketplace.

Is there support, and are there SLAs?

Support comes straight from the developer, on a best-effort basis, usually within 1–2 business days. No fixed response or resolution times (SLA) are promised. The support path is on every docs page.

Will the apps run on my Jira?

The apps are built for Jira Cloud and run on Atlassian Forge. Jira Data Center and Server are not supported. Permissions are minimal and documented per app.

What does a custom tool cost?

From €1,400, for example "From Excel to a tool". You'll get your final fixed quote before the project starts; no VAT is shown under the German small-business exemption (§ 19 UStG).

Who is Dangel Studio not the right fit for?

Large projects that need a full agency team or 24/7 support, plus Jira Data Center. If you value focused tools and one direct point of contact, we'll get along great.

A question about an app, or a tool in mind?

A support question about one of the apps, feedback, or an idea for a tool of your own: tell me briefly what it is. The reply comes straight from the developer.
