NeueCode vs Refact.ai: Supported Sovereign On-Prem Coding

Refact.ai is an open-source, self-hostable autonomous coding agent that plans, writes, tests, integrates with engineering tools, learns from interactions, and can run on-premises on your own models. For teams that want full source control of the tool itself and have the capacity to run and maintain it, that openness is a real advantage.

Open source shifts maintenance, security patching, and support onto you — and Refact’s main repository was archived in 2026, a real continuity risk for a risk-averse buyer. NeueCode is a supported commercial product built for that buyer: a compiled native backend, hardware-bound licensing, and — the core difference — provable sovereignty. In strict mode a deny-by-default egress broker signs an offline-verifiable, per-run non-egress manifest, and a tamper-evident, hash-chained Agent Flight Recorder lets your own auditor verify offline exactly what the agent did.

NeueCode terminates identity on your own directory (Active Directory / LDAP / SAML 2.0), ships native English and Arabic with full RTL, and maps its compliance evidence — mapped, not certified — to the EU AI Act, DORA, NIS2, and ISO 42001, with a scoped on-prem pilot. If you want open source and can own it, Refact.ai is a fair option; if you need a supported, provable sovereign agent, choose NeueCode.
