About dflux
dflux builds 5G SA tooling.
We are a company that speaks 3GPP on the wire. The public product is Runik — an on-prem tester for 5G SA cores.
Mission
Honest tooling for Standalone networks
dflux ships an on-prem 5G SA tester: declarative YAML, CI exit codes and JUnit. We document what we support — and what we don't. The unsigned community floor is NGAP, SBI, REST, and JUnit, up to 1000 UE.
Expertise
Built close to the wire.
The tools are only as good as their grasp of the protocols underneath. Ours are built around 3GPP control- and user-plane signaling and the service-based interfaces that tie a 5G core together.
Protocol depth
- NGAP (N2) — gNB ↔ AMF over SCTP
- NAS 5G (N1) — registration & sessions
- GTP-U (N3) — user-plane tunneling
- SBI / HTTP-2 — service-based interfaces
- Diameter — S6a / Gx / Rx
- PFCP (N4) — licensed on Runik, not the unsigned floor
Standards we build to
- 3GPP Release 16 / 17 / 18
- TS 38.413 — NGAP
- TS 24.501 — NAS for 5GS
- TS 29.281 — GTP-U
- TS 29.500-series — SBI
- RFC 6733 — Diameter base
How we work
- On-prem CLI — not a cloud console
- Optional UI embeds next to the binary
- Catalog counts are generated from source
- Community floor is unsigned and documented

Principles
How we build.
A few decisions shape every tool we ship.
Runnable over theoretical
If it isn't something you can start with a binary, we don't ship it as a product page.
Doc-accurate claims
Protocol lists, catalog counts, and scope limits are generated from the source tree — not typed into a slide.
On-prem by default
You run the binary. An optional UI can embed next to it. We don't sell a cloud console here.
