If you came here looking for Blitz for Marvel Rivals, the short answer is that NetEase banned it and you should not be running it. The longer answer is worth a minute, because it explains why it got banned, what that means for your account, and what to use instead that does not carry the same risk.
What happened to Blitz
Blitz, the assistant app that also covers League of Legends, Valorant, and Apex Legends, added Marvel Rivals support not long after the game launched. NetEase banned it.
Per NetEase's notice on third-party plugins, Blitz injects into the Marvel Rivals game process, which let it read real-time information the developers treat as confidential, including in-match damage and healing for players you are not meant to have those stats on. NetEase framed it as cheating software and called out three things specifically: live damage and healing pulled from the game process, hero-ban advantages beyond the in-game pick-ban system, and ultimate-prediction tools.
Whether you would personally call any of that cheating does not change the practical decision. NetEase banned the app, and running a workaround or an unofficial re-release puts your account at risk.
Why it matters for your account
If you are here because you installed Blitz, or you are about to, read this part first. Marvel Rivals is tied to a NetEase account, and NetEase bans for third-party software. Even where enforcement is uneven, the long-term risk is real. Do not run Blitz with Marvel Rivals open, do not install patched versions, and do not trust a forum thread swearing it is safe again. If you already have it, the cheap move is to uninstall it cleanly.
Overwolf apps are a different category. They read game events through an officially supported pipeline instead of injecting, and NetEase has treated those separately.
How Counterwatch is different
Counterwatch is a Windows app distributed through Overwolf, and that distinction is the whole point.
Overwolf does not inject into the game. It reads game events through a channel that both Blizzard and NetEase have green-lit for third-party companion apps, which is how an Overwolf app can show live match info without tripping the ban NetEase applied to Blitz. Counterwatch uses that game-events API rather than process injection, does not show the confidential live stats NetEase flagged (no live damage or healing for players you should not have it on), and does not ship ultimate prediction. What it focuses on is the pick: counters, synergy and team-up pairs, map-specific hero stats, and pre-match and mid-match decisions built from community data.
None of that puts your account at risk. The app is on Overwolf's public store, and the numbers come from aggregated opted-in players over many matches, not from reading the enemy team's live game state.
What you get instead
If Blitz was on your radar for the overlay and companion features, here is the Counterwatch version, all inside NetEase-approved boundaries:
- An in-game overlay that reads enemy picks live and surfaces counters, swaps, and a win-chance read for your lineup.
- A second-screen window for a spare monitor.
- Community win rates at the tier-list level, per hero, filterable by rank and mode.
- Hero-vs-hero matchup data across the whole roster, built from tens of thousands of tracked matches.
- Synergy and team-up pair data, including the team-up bonus system.
- A team builder that scores a full lineup on counters, synergy, and map performance.
- Per-map hero stats for the map you actually loaded into.
All of it free.
The one thing Counterwatch does not do for Marvel Rivals is deep profile scouting on the other players in your lobby. We show ranks, not full profiles. If that is specifically what you want, Marvel Rivals Tracker covers it, and we have a separate comparison for that. For a NetEase-safe way to pick heroes better before and during a match, and to track your own sessions and stats while you do, the Counterwatch app is the one to install. The team builder and tier list also run in a browser with no install if you want to look first.
