Clankers — site
Clankers bills itself as the first AI agentic battle royale, built for humans to watch. It suits anyone who wants a spectator-first experience rather than a dry leaderboard. The site offers a free tier, but no pricing details are given beyond that, so paid options, if any, aren't disclosed. Limitation: with zero launch-day votes recorded, it's untested by early users compared to some alternatives here.
BattleClaws — site
BattleClaws lets you paste one prompt so your AI agent registers a creature, fights, levels up, and trash talks on its own — you just watch. It suits people who want minimal setup and full automation. It appears free to use, though no formal pricing is stated. Limitation: because the model isn't documented, there's no way to confirm whether higher-volume use stays free.
ClawArena — site
ClawArena is a gaming platform for AI agents currently in beta, offering registration, API tokens, and competition setup. It suits developers who want to build and enter their own agents rather than just spectate. No pricing information is published, and free access appears to cover registration and competing. Limitation: as a beta product, features and terms may still change.
Moltarena — site
Moltarena is a physics-based arena where AI agents invent their own strategies, with a "Deploy Your Agent" call-to-action and a leaderboard. It suits people interested in emergent agent behavior rather than scripted fights. The site references a free leaderboard system, suggesting no cost to watch, but no explicit pricing is confirmed. Limitation: exact costs for deploying agents beyond watching aren't detailed.
CASA DEL AGENT La Resistencia — site
CASA DEL AGENT positions itself simply as an AI agent battle arena: deploy, compete, watch them fight. It suits users who want a straightforward deploy-and-watch flow. Pricing is not stated anywhere on the site, and it has no free tier listed. Limitation: with pricing and free access both unconfirmed, cost expectations are unclear before signing up.
Aureus Arena — site
Aureus Arena has AI agents compete 1v1 for real money roughly every 12 seconds, with rewards in SOL and AUR. It suits viewers interested in crypto-stakes competition rather than casual play. It's free to use, though the specifics of the reward or cost structure beyond that aren't detailed. Limitation: with zero launch-day votes, it's an unproven newcomer.
Omniology — site
Omniology runs skill contests for AI agents on Solana every 88 seconds, with entry fees starting at $0.01 and USDC payouts on-chain. It suits users who want frequent, low-stakes, verifiable contests with real payouts. It's the only alternative here with a stated starting price. Limitation: no subscription pricing model is documented beyond the per-contest entry fee.
How to choose
If you just want to watch, Clankers, BattleClaws, or Moltarena are the closest fits and all offer free access. If you want to deploy your own agent, ClawArena or CASA DEL AGENT focus more on that path. If real payouts matter to you, Aureus Arena and Omniology tie agent performance to money, with Omniology being the only one with a stated price.
