A simple API. No sales calls. Try it in 5 minutes.
Kommt is in early access. We’re building data-driven delivery predictions for German e‑commerce — one endpoint, one API key, no lock-in. Every response includes a confidence score and the number of data points behind it, so you decide when to trust it.
A note from the founder
“I’m building Kommt openly because every German checkout deserves a better answer than ‘3–5 business days.’ The free tier stays free. Paid plans fund the data pipeline and the servers. If you try it and something’s wrong, email me directly — I’ll fix it.”

Every vague estimate costs you a customer
While you show “3–5 business days,” your competitors show Thursday by 2pm. The gap between vague and precise is measured in lost revenue.
Vague delivery windows kill conversions
Your checkout says "3–5 business days." Your competitor says "Thursday by 2pm." Customers pick the shop that gives them certainty — every single time.
Every unclear estimate is a lost sale.
Carrier integrations are an engineering black hole
DHL, Hermes, DPD, GLS, UPS, Amazon — each with different APIs, different formats, different failure modes. Your team spends months building what should take minutes.
Engineering time burned on solved problems.
Without real data, predictions are fiction
Carrier SLAs are marketing numbers, not delivery predictions. Without millions of actual tracking data points per postal code, your estimates are guesses dressed up as promises.
Broken promises erode trust permanently.
“62% of German online shoppers say delivery speed information directly influences their purchase decision.”
— Metapack State of Delivery Report
It doesn’t have to be this way
Everything you need, nothing you don't
We built Kommt to do one thing exceptionally well: predict delivery windows for German carriers.
Confidence Scores
Every prediction comes with a confidence score and the number of data points behind it. Your code decides when to trust it.
Fast Enough for Checkout
Hosted in Germany. Typical responses are well under a second — fast enough to call inline on product or checkout pages.
Self-Improving
The dataset grows every hour from real German deliveries. Predictions for a given PLZ get sharper over time.

Frequently asked questions
Everything you need to know about Kommt.
Kommt is in early access and our delivery dataset is growing daily. We're honest about that: every API response includes a confidence score (0–0.95) and the number of historical data points behind it, so your code can decide when to use the prediction and when to fall back to a generic estimate.
DHL, Hermes, DPD, GLS, UPS, and Amazon Logistics — the six major German carriers, covered with a single integration.
Those are full-suite post-purchase platforms with sales cycles and onboarding. Kommt is one REST endpoint you can integrate in an afternoon. No dashboard you have to use, no contract, no vendor lock-in.
No. The free tier includes 500 requests per month with no credit card required. Upgrade when you're ready.
Yes. Paid plans are month-to-month via Mollie. Cancel from your dashboard and you'll keep access until the end of your billing period, then drop to the free tier automatically.
Hosted in Germany. Typical responses are well under a second from anywhere, and much lower from inside Germany. We're a small team — if something breaks, you'll hear from the founder directly.
