The record

Purpose: Mica is a cross-platform Minecraft modpack launcher that fetches a pack manifest, downloads its required files, verifies them by SHA-1, and launches the game.
Loaders: It supports Forge, NeoForge, Fabric, and vanilla Mojang versions.
Import formats: It imports Modrinth .mrpack files, MultiMC or Prism Launcher instance folders, and Mica-format ZIP exports.
Pack sources: The launcher can add packs from Mica manifest URLs and Modrinth, CurseForge, or TechnicPack project URLs.
Client and server modes: It runs as a desktop GUI client or in headless server mode; native app builds support client mode only.
Installers: The README lists EXE or MSI installers for Windows, DMG or PKG for macOS, and DEB or RPM for Linux.
Integrity checking: Modpack files can include SHA-1 hashes for verification, and setting a file hash to -1 skips that check.
URL handling: The launcher registers an mmcl:// URL scheme for adding packs, installing and launching packs, launching vanilla versions, and opening installed packs; users can disable it in Settings.
Auto-join: A pack manifest can specify a default multiplayer server host and optional port and display name for auto-join on play.
RAM requirement: A pack can specify minimum RAM, and the launcher refuses to start it when the configured maximum RAM is below that amount.
License: The public GitHub repository is marked GPL-3.0 licensed.
Support: The README directs users to open a GitHub issue for bugs or feature requests and a pull request for code changes.
Maker profile: The GitHub organization links to micatechnologies.com, but its opened page exposed no readable company details.
Mod loaders: It supports Forge, NeoForge, Fabric, and vanilla Mojang versions.
