Neptune DXP is a proven SAP-native low-code platform — inside an SAP estate, it is hard to beat. Archiet solves the layer above any single ecosystem: a living model of your architecture that audits risk, proves compliance, modernizes brownfield systems, and generates production code you own — on whatever stack you choose.
| Dimension | Archiet | Neptune DXP |
|---|---|---|
| Core identity | Architecture Intelligence Platform — a living model of your systems that audits, proves compliance, builds, and modernizes | SAP-native low-code Digital Experience Platform (DXP) for enterprise app and AI-agent development |
| Ecosystem anchor | Stack-agnostic: 9 boot-verified web stacks (Flask, FastAPI, Django, NestJS, Laravel, Go, Java, Rails, .NET), desktop, and domain-aware delivery | SAP-certified across ECC, S/4HANA, ABAP Cloud — deep Fiori/UI5 strengths; also connects to non-SAP systems |
| What you own at the end | Generated source code in your repo — reviewable, deterministic, no platform runtime dependency | Apps that run on the Neptune DXP platform runtime, licensed per platform terms |
| Citizen development | Governance layer over ANY citizen/AI-built app regardless of tool: architecture audit, compliance mapping, architecture-grade regeneration | "Suits & Geeks" multi-persona builder — no-code, low-code, and pro-code personas building on Neptune itself |
| Compliance evidence | SOC 2, ISO 27001, GDPR, HIPAA, DORA, NIS2, PCI-DSS control matrices, gap reports, and audit documentation generated from the model | Enterprise platform controls and governance features; compliance documentation is your responsibility |
| Brownfield approach | Model the estate you have (docs, diagrams, plain English) → risk audit → module-by-module governed replacement | Reuse existing SAP investments and business logic; build new experiences on top of what runs |
| Architecture model | Formal, living model (ArchiMate 3.2-aligned genome) — the single source every output derives from | App-level development artifacts; architecture governance is external to the platform |
| Getting started | Self-serve: free architecture audit in ~2 minutes, no signup; free plan for generation | Enterprise sales-led; 850+ customers, strong partner network (100+ certified partners) |
Neptune DXP details based on public materials as of mid-2026 (neptune-software.com, SAP partner listings, analyst reviews).
Neptune earned its position: 850+ enterprises use it because building modern experiences on SAP business logic is genuinely hard, and Neptune makes it fast while respecting what already runs. If that is your problem, evaluate Neptune on its home turf — we will not pretend otherwise.
Archiet answers a different question: who governs the architecture of everything else? The heterogeneous estate outside any single vendor's boundary — the AI-built internal tools, the aging systems nobody documented, the new products that must pass a security review next quarter. Archiet's living model turns that sprawl into audited, compliance-evidenced, deterministically generated systems whose source code lands in your repository, not in a runtime you license.
Neptune DXP is an enterprise low-code platform from Neptune Software, best known for being SAP-native: fully SAP-certified across ECC, S/4HANA, and ABAP Cloud, with strong Fiori/UI5 app development. It serves 850+ customers and 4M+ users with a multi-persona approach ("Suits & Geeks") spanning no-code, low-code, and pro-code development, and it also connects to non-SAP systems.
If your estate is anchored in SAP and your goal is building modern experiences and workflow apps on top of SAP business logic, Neptune is a strong, proven choice — that is its home turf, and Archiet does not compete inside it. Its SAP certification and partner ecosystem are genuine advantages there.
When the problem is architecture-level rather than SAP-app-level: you need to understand and modernize systems across a heterogeneous estate, produce compliance evidence auditors accept, govern apps your teams built with AI tools and assorted low-code platforms, or generate production systems whose source code you own outright — with no platform runtime attached.
Neptune governs citizen development by bringing builders onto Neptune — one platform, multiple personas. Archiet governs citizen development wherever it already happens: apps built with AI coding tools, spreadsheets-turned-apps, or any low-code vendor get an architecture audit, compliance mapping, and a graduation path to architecture-grade generated code. One is a destination; the other is a governance layer.
Mostly they solve different jobs. A large enterprise could sensibly run both: Neptune for SAP-anchored app delivery, Archiet as the architecture intelligence layer across the whole estate — auditing, proving compliance, and generating owned code for the systems that live outside the SAP boundary.
