    About

    Immersive Portal turns portals into continuous, live-view passageways, replacing the usual purple portal surface with portals that can be placed at different sizes, positions, orientations, and destinations, including within the same dimension. Lighting a standard obsidian frame creates a seamless, two-way portal cluster, with destination searching, automatic construction of the far-side frame, existing-frame linking, and the familiar 8:1 Nether coordinate mapping; crouch-igniting a frame still creates a vanilla-style portal. Players and other entities, including items, arrows, ender pearls, animals, boats, and minecarts with passengers, can cross while preserving momentum, and portals can display portals within them up to five levels deep. Commands support custom, round, scaled, rotating, animated, and global portals, while the creative-mode portal wand and command sticks let players create portals by selecting three corners, reshape them, and copy and paste them. Mirrors, a helper block for linking same-dimension frames, and datapack-defined portal types let creators specify frame blocks, ignition items, target dimensions, and forms such as flipping-floor, scaling-square, and one-way portals. Worlds can be stacked with portals at their boundaries, and the mod also offers extra dimensions such as skylands and chaos terrain; the far side of each portal is chunk-loaded, lit, and ticking on the server. The optional Passthrough Extras feature can connect redstone circuits and rails across portal surfaces, let minecarts travel smoothly through them, and render blocks placed across a portal seam on both sides.

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Starts other programs
    It can start another program on your computer. Only in its files for Fabric 1.21.11, 26.2 to 26.3; NeoForge 1.21.11 to 26.3; Forge 1.21.11 to 26.3; Quilt 1.21.11 to 26.3.
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for Fabric 1.21.11, 26.2 to 26.3; NeoForge 1.21.11 to 26.3; Forge 1.21.11 to 26.3; Quilt 1.21.11 to 26.3.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Fabric 1.21.11, 26.2 to 26.3; NeoForge 1.21.11 to 26.3; Forge 1.21.11 to 26.3; Quilt 1.21.11 to 26.3. See Privacy

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · All 11 latest files checked, last on 18 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      11 latest files: the newest file for each Minecraft version and loader. All 11 are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.
      Read without running it
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends about you

    We read its code without running it: it contacts 1 web address while you play.

    Like any connection, each address it contacts sees your IP address.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · All 11 files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of all 11 files, for recent Minecraft versions. See each file in Releases
    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.
      Purpose not known.

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its texts, files and images and found none.

    We have not read its code history yet.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
