About dflux
Built for people who run 5G, not slide decks.
We build tools that protocol engineers, lab operators, and platform teams can actually run — in CI, on a laptop, and in front of real NFs.
Mission
Honest tooling for Standalone networks
dflux is a suite of 5G SA tools: a protocol tester, a signaling proxy, a lab core, and one operator console. Products stay headless. The console is management plane only. We document what we support — and what we don't.
The suite
Four products. One operator console.
Test, secure, and run on the wire — operate from dflux Console. Products share a protocol vocabulary and stay independent.
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
- PFCP (N4) — SMF ↔ UPF
- GTP-U (N3) — user-plane tunneling
- SBI / HTTP-2 — service-based interfaces
- Diameter — S6a / Gx / Rx
Standards we build to
- 3GPP Release 16 / 17 / 18
- TS 38.413 — NGAP
- TS 24.501 — NAS for 5GS
- TS 29.244 — PFCP
- TS 29.500-series — SBI
- RFC 6733 — Diameter base
How the tools fit
- Console — single operator UI
- Runner — drive protocols as a tester
- EdgeGuard — govern SBI & Diameter
- TinyCore — implement the lab core
- Headless products; management plane for UI
- Together, or best-of-breed alone
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 or a compose file, we don't ship it as a product page.
Doc-accurate claims
Flow counts, protocol lists, and scope limits are generated from the source tree — the 452 on this page was counted by a script, not a marketer.
Headless by default
Data-plane tools stay CLI/API-first. One console for operators — never a second SPA per binary.
Honest about maturity
TinyCore is in early beta and we say so on its own page, next to the list of what doesn't work yet. Production-grade is where we're driving it — not a claim we make before it's earned.
