Company
An engineering company in Istanbul
Digital Cosmonot was founded in Istanbul in January 2021. Until 2025 we designed, migrated and operated enterprise API gateway infrastructure for banks, insurers and public institutions in Türkiye: work where a missed request is an incident and every change needs an owner. In 2026 we put what we learned there into our own product, G8. We no longer resell other vendors' products.

How we work
Practices you can ask us about
We sell what we build
Since 2026 we sell only our own product. What we recommend, we built, and we support.
Tested against the real thing
Our tests run against live gateway nodes, Elasticsearch, OpenSearch and Prometheus, not mocks of them.
A fix comes with its proof
Every fix ships with the test that failed before it, so the same fault cannot quietly return.
The builders answer
Support requests reach the engineers who write G8, in Turkish or English.
Your data stays in your network
G8 runs only in your infrastructure. Request records go to your own store, with sensitive fields masked first.
Every change leaves a record
Each configuration change is recorded with its before and after, secrets masked.
