LexNebulis
What it is
LexNebulis is a free, self-hosted legal practice management platform aimed at small law firms with 1 to 50 users. It brings client and matter records together with document management, calendars, time tracking, billing and trust accounting. Legal workflows include conflict checks, client intake, document templates and generation, e-signatures and a client portal. Billing supports LEDES 1998B and 2000 export, UTBMS codes and electronic invoice submission. Listed integrations cover Stripe and LawPay payments, QuickBooks and CSV accounting export, and Google Drive, Dropbox, Box and OneDrive storage. Security features include encryption, bcrypt password hashing, JWT authentication and TOTP or WebAuthn/FIDO2 two-factor authentication. Its append-only audit log uses SHA-256 hash chaining to make tampering or deletion detectable. The software is free for commercial use under Apache License 2.0. Deployment requires Docker and Docker Compose v2, at least 2 GB RAM and 10 GB disk space. Installation calls for a Linux server, with Ubuntu 22.04 or later recommended; macOS is specified for development.
