ReplayCore: Minecraft Replay Plugin for Anti-Cheat Evidence [ All posts](https://www.zcraftstudios.com/blog) # ReplayCore: Minecraft Replay Plugin for Anti-Cheat Evidence ZCraft StudiosNov 9, 2026 ReplayCore records your Minecraft server so staff can watch fights in 3D in the browser, with anti-cheat flags, combat analysis and a free plan. ## In this guide - [Why a replay helps moderation](#why-a-replay-helps-moderation) - [What ReplayCore does](#what-replaycore-does) - [Supported servers and versions](#supported-servers-and-versions) - [How installation works](#how-installation-works) - [Anti-cheat and other integrations](#anti-cheat-and-other-integrations) - [Storage and plans](#storage-and-plans) - [Performance: what ReplayCore reports](#performance-what-replaycore-reports) - [Use replays in a moderation workflow](#use-replays-in-a-moderation-workflow) - [Privacy and rules](#privacy-and-rules) - [How to test it before you commit](#how-to-test-it-before-you-commit) - [Replay plugin or client mod?](#replay-plugin-or-client-mod) - [Frequently asked questions](#frequently-asked-questions) - [Related reading](#related-reading) **Quick answer:** ReplayCore lets staff **watch recorded Minecraft fights back in 3D in their browser**, with a timeline, a free camera and per-hit combat analysis. It works with anti-cheat plugins such as **Grim, Vulcan and Spartan**, shows their flags on the replay timeline, needs **no client mod**, and has a **free plan**. A flag tells staff something happened, and a replay shows them the fight, so bans rest on footage and not on a flag alone. _Disclosure: ReplayCore offered ZCraft Studios a Pro account to test and a creator program with a commission, so we may earn money if you buy through our link or code. We wrote this from ReplayCore's public pages and documentation, last checked November 2026, and have not benchmarked it on a production server. ReplayCore has said it will give ZCraft readers 10% off through a creator code, and we will add the code here when it is live. Features, plans and versions change, so confirm on their site._ ![ReplayCore browser replay viewer, screenshot supplied by ReplayCore](https://esrjajilhtjdleheettk.supabase.co/storage/v1/object/public/product-images/Blogs/IMG_4794.png) _ReplayCore's browser replay viewer.

Staff then guess from chat reports and logs, and good players can get punished by false positives. A replay lets a moderator watch the actual fight, from any angle, and decide. | Without a replay | With a replay | | -------------------------------------------------- | --------------------------------------- | | A flag name and a violation count | The fight itself on a timeline | | Staff rely on screenshots and clips from players | Staff watch the server's own recording | | Appeals become one person's word against another's | The reviewer can watch the same footage | | Hard to explain a ban | A clip supports the decision | This fits the approach in [Best Minecraft Anti-Cheat Plugins](https://www.zcraftstudios.com/blog/minecraft-anticheat-plugins-compared): run anti-cheat in alert-only mode first, then review flags before you punish. ## What ReplayCore does | Feature | What it does | | ---------------- | --------------------------------------------------------------------------------------------------------------- | | Browser playback | Watch replays on a computer or phone with no Minecraft client | | Free camera | Fly around, or watch through any player's eyes | | Player details | Click a player to see health, inventory, armour and effects at that moment | | Portals | The replay follows players into the Nether and the End | | Combat analysis | Lists every melee hit with the tick, who hit whom and estimated reach, with playback that can pause on each hit | | Anti-cheat flags | Grim, Vulcan and Spartan flags appear on the timeline | | Staff roles | Owner, admin, staff and member roles, with per-feature access | | Branding | Paid plans can use your own logo, colours and domain | | Cloud storage | Replays upload in the background and play away from your game server | | API | REST API and an open-source Java SDK, plus a plugin API for bookmarks | Reach figures are estimates to help staff review a fight. They do not prove that anyone is cheating, so combine them with the flags and what you see in the replay. ![ReplayCore replay and combat analysis, screenshot supplied by ReplayCore](https://esrjajilhtjdleheettk.supabase.co/storage/v1/object/public/product-images/Blogs/IMG_4795.png) _A replay with the combat view. Screenshot provided by ReplayCore._ ## Supported servers and versions ReplayCore lists these: | Item | Details | | ------------------ | -------------------------------------------------------------------------------- | | Minecraft versions | Java Edition 1.8.8 through 26.3 | | Server software | Paper, Purpur, Folia and Leaf | | Spigot | Verified on 1.8.8 to 1.12.2, 26.2 and 26.3\. On Spigot 1.13 to 1.21.x, use Paper | | Folia | Verified on 1.21.11 through 26.3 | | Download | One file for all supported servers | Confirm your exact version in their system requirements. See [Update a Minecraft Server to 26.1+](https://www.zcraftstudios.com/blog/minecraft-26-1-server-update-guide) and [Folia vs Paper vs Purpur](https://www.zcraftstudios.com/blog/minecraft-server-software-paper-purpur-folia). ## How installation works According to ReplayCore, you put a single file, `ReplayCoreLoader.jar`, in your plugins folder and start the server: 1. Create a free ReplayCore account and link your server. 2. Stop the server and put `ReplayCoreLoader.jar` in `plugins/`. See [How to Add Plugins](https://www.zcraftstudios.com/blog/how-to-add-plugins-to-minecraft-server). 3. Start the server. The Loader downloads the recorder that matches your server and, on 1.13 and newer, installs PacketEvents for you. 4. Check the console for errors. See [Plugin Not Loading?](https://www.zcraftstudios.com/blog/minecraft-plugin-not-loading-fix). 5. Record a short test session and watch it in the browser. Automatic updates are on by default, and a new recorder installs at the next restart. You can turn them off and run `/replaycore update` yourself. Back up before updating, and test updates on a staging copy. See [Update Plugins Safely](https://www.zcraftstudios.com/blog/minecraft-server-plugin-update-checklist). ## Anti-cheat and other integrations | Group | Integrations | | -------------- | ----------------------------------------------------------------------------------- | | Anti-cheat | Vulcan, Spartan, Grim | | Minigames | BedWars1058, MBedwars, Screaming BedWars, Realized Duels and Duels Optimised | | Staff tools | Vanish plugins (SuperVanish, PremiumVanish, EssentialsX), LuckPerms, PlaceholderAPI | | Sharing | Discord links and signed webhooks | | Custom content | ItemsAdder, Oraxen, Nexo, MythicMobs and ModelEngine | ReplayCore does not post to a Discord channel by itself yet, and sends replay links and webhooks you can use. See [Vulcan Setup Guide](https://www.zcraftstudios.com/blog/vulcan-anticheat-setup-guide), [LuckPerms Setup Guide](https://www.zcraftstudios.com/blog/luckperms-ranks-setup-guide) and [PlaceholderAPI Setup](https://www.zcraftstudios.com/blog/placeholderapi-setup-guide). ## Storage and plans | Plan | Storage | Replay retention | | ---------- | --------------- | ---------------- | | Free | 1 GB | 14 days | | Starter | 50 GB | 30 days | | Pro | 150 GB | 60 days | | Enterprise | Agreed with you | Agreed with you | Replays are written to disk on your server, compressed and uploaded in the background, and you can delete one at any time. Check the pricing page for current prices and what each plan includes. ## Performance: what ReplayCore reports ReplayCore reports a test of version 1.5.41 on a PaperSpigot 1.8.8 server with 100 bot players for ten minutes. With recording on, two runs averaged 19.77 and 19.78 TPS, and the same test with no plugin averaged 19.77 TPS. That is one test on one machine, so measure your own server with [spark](https://www.zcraftstudios.com/blog/how-to-read-spark-profiler-minecraft) before and after. See [TPS vs Ping vs FPS](https://www.zcraftstudios.com/blog/minecraft-server-tps-vs-ping-vs-fps). ## Use replays in a moderation workflow 1. **Anti-cheat flags** a player in alert-only mode. 2. **Staff open the replay** from the flag on the timeline. 3. **Review the fight** from several angles, using combat analysis as a guide. 4. **Decide** on a warning, temporary ban or no action. 5. **Attach the replay link** to the case. See [Discord Ticket Systems](https://www.zcraftstudios.com/blog/minecraft-server-discord-ticket-workflow). 6. **Use the same footage in appeals.** See [Ban Appeal Process](https://www.zcraftstudios.com/blog/minecraft-server-ban-appeal-process). 7. **Record the punishment** in your punishment plugin. See [AdvancedBan](https://www.zcraftstudios.com/blog/advancedban-setup-guide) or [LiteBans](https://www.zcraftstudios.com/blog/litebans-setup-guide). Train staff to treat a replay as evidence, not a verdict. See [Staff Training Checklist](https://www.zcraftstudios.com/blog/minecraft-server-staff-onboarding) and [Dealing With Cheaters](https://www.zcraftstudios.com/blog/minecraft-server-cheaters). ## Privacy and rules Recording players is a moderation decision, so be open about it: - State in your rules that sessions may be recorded for moderation. See [Server Rules Template](https://www.zcraftstudios.com/blog/minecraft-server-rules-template-examples). - Decide who can watch replays, using staff roles. - Keep retention short, and delete replays that are no longer needed. - Check your local privacy law and ReplayCore's privacy policy and data processing terms. - Do not share replay links publicly without thinking about who appears in them. ## How to test it before you commit 1. Open the [live demo](https://replaycore.com/en/demo) to see a real replay. 2. Install it on a staging server. See [Staging Environment Guide](https://www.zcraftstudios.com/blog/minecraft-server-staging-environment-guide). 3. Record a test fight with two accounts. 4. Trigger an anti-cheat flag and find it on the timeline. 5. Review the combat panel and the camera options. 6. Check TPS with [spark](https://www.zcraftstudios.com/blog/how-to-read-spark-profiler-minecraft). 7. Decide whether the free plan or a paid plan fits your storage and retention needs. ## Replay plugin or client mod? Client-side replay mods record what one player sees. ReplayCore records on the server, so staff can review any fight without a mod and the footage does not depend on a player's client. ReplayCore also publishes its own comparison pages if you want to compare options. ## Frequently asked questions **What is ReplayCore?** A Minecraft server plugin and web service that records the server and lets staff watch replays in a browser. **Does it need a client mod?** No, replays play in the browser. **Does it work with Grim and Vulcan?** Yes, it adds their flags to the replay timeline, along with Spartan. **Is there a free plan?** Yes, with 1 GB of storage and 14-day retention. **Which Minecraft versions does it support?** 1.8.8 through 26.3 on Paper, Purpur, Folia and Leaf, with Spigot support for some versions. **Does recording cause lag?** ReplayCore reports a test with no measurable TPS change, but test your own server. **Does it replace anti-cheat?** No. It helps staff review what anti-cheat flags. **Is a replay proof of cheating?** It is evidence.
