Panelica is a next-generation Linux server management panel built from scratch in Go and React, designed to replace heavyweight legacy panels like cPanel and Plesk. Modern stack, API-first — every UI action is also a REST API call AND a CLI command.
-------- KEY DIFFERENTIATORS --------
5-LAYER ISOLATION (industry-leading)
• Cgroups v2 — CPU, memory, IO, PID limits per user
• Linux Namespaces — CageFS-style per-user rootfs
• SSH Chroot — SFTP-only or full bash + chroot
• PHP-FPM per-user per-version pool (open_basedir)
• UID/GID isolation, home 0700, sudo-as-user ownership
TRIPLE INTERFACE
• Internal REST API (panel UI)
• External REST API with HMAC-SHA256 auth
• CLI (panelica) — full endpoint parity
BUILT-IN MODERN TOOLKIT
• WordPress Toolkit — install, clone, staging, WP-CLI
• Docker Manager — per-user containers, compose
• Git Deploy — deploy from any Git repo
• Migration from cPanel / Plesk / DirectAdmin (file + DB hash preservation, no password resets)
• Cloudflare native: Origin Cert (15-year), DNS-01 wildcard, auto proxy detection
SMART SSL AUTOMATION
• 1-click Auto-Issue with strategy selector (CF Origin / DNS-01 wildcard / SAN aggregate / HTTP-01 / TLS-ALPN)
• OCSP stapling, HSTS preload, TLS 1.3 by default
• Self-healing reconciler
PRODUCTION STACK (isolated under /opt/panelica/)
• Web: nginx 1.28 + Apache 2.4
• PHP: 8.1 ? 8.5 parallel + ionCube 15.5
• Databases: PostgreSQL 17 + MySQL 8
• Mail: Postfix + Dovecot + DKIM + ClamAV
• DNS: BIND9 with Cloudflare bridge
• FTP: ProFTPD with chroot + per-user quota
• Cache: Redis 7
• Security: ModSecurity + OWASP CRS, Fail2ban, AppArmor, nftables
OPERATIONS
• Incremental backups (per-domain, per-DB, snapshots)
• Real-time bandwidth + disk quota
• 31-language UI
• RBAC: ROOT ? ADMIN ? RESELLER ? USER
• 246 documented API endpoints
• Single Go binary backend — minimal RAM
-------- PANELICA vs cPanel --------
• 5-layer isolation vs cgroups-only
• REST API native vs XML whitelist
• Single Go binary vs ~30 cpsrvd processes
• 31 languages vs ~10
• Built-in Docker (cPanel: paid plugin)
• Modern React 19 UI, mobile-responsive
-------- PANELICA vs Plesk --------
• Open architecture — every config visible in /opt/panelica/
• Modern Go stack vs PHP control plane
• Native Cloudflare Origin Certificate
• Per-user per-version PHP with isolated FPM pools
• Full CLI parity with UI
• Lower licensing cost
Comments and Reviews
Very good project.
I like panelica but i dont understand
Panelica: Real proof, strong commitment, full trust.
I love what the founder and the team are doing. Nice job.
I like Panelica because it has 5-layer isolation capabilities, native Docker support, and API prioritization.
