Augur is a free, open-source Mac desktop application that runs a self-hosted Ethereum prediction market platform entirely on your own machine, combining the Augur interface and its backend node into a single installable package.
What is Augur?
Augur is a decentralised prediction market protocol built on Ethereum, and this desktop app is the local-first way to interact with it — no third-party server, no hosted intermediary, just your Mac running the full stack. When you launch the app, it brings up both the web-based Augur UI and the Augur Node service simultaneously, wiring them together automatically so you land on a working interface without any command-line juggling.
The significance of that is easy to understate. Running your own node means the market data you see is pulled and verified by software you control. For anyone who takes decentralisation seriously, that's the whole point — the app is the shortest path between "I want to participate in on-chain prediction markets" and actually doing it.
What does Augur do best?
Augur excels at collapsing a genuinely complex local-node setup into a double-click install. Spinning up an Ethereum-based dapp with its own indexing layer would normally mean installing dependencies, configuring ports, and keeping two terminal windows alive. Here it happens invisibly behind a native Mac app wrapper.
The Augur UI itself covers the core prediction-market workflow: browsing open markets, placing long or short positions, reporting outcomes, and claiming winnings after resolution. Because the node syncs directly from the Ethereum chain, market state is authoritative — not cached by a centralised API that could go stale or get taken down.
Is Augur free?
Yes, the desktop application is completely free to download and open-source under a public licence. The underlying Augur protocol does involve real ETH for gas fees and REP tokens for market participation and reporting, so there are on-chain costs when you actually trade or stake — but the software itself costs nothing, and you are never paying a platform subscription.
Who should use Augur?
Augur is squarely aimed at people who are already comfortable with Ethereum wallets and understand that prediction markets carry real financial risk. It is not a casual weekend experiment — syncing the node takes time, the UI assumes familiarity with concepts like shares, settlement, and REP staking, and interacting with mainnet means you are moving real assets.
That said, if you are a developer exploring decentralised finance protocols, a researcher studying information markets, or simply a crypto-native who wants to trade on event outcomes without routing through a centralised book, Augur is one of the few options that lets you do it with full local sovereignty. Analysts who want to run the node for data purposes — scraping market resolution history, studying crowd forecasting accuracy — also benefit from a local install that doesn't depend on any third party's uptime.
What are the best Augur alternatives?
Within the on-chain prediction market space, Polymarket is the most active competitor today — browser-based, Polygon-native, and far more accessible to non-technical users, but you are trusting their hosted infrastructure. Manifold Markets offers play-money forecasting with a much lighter onboarding path and is a better fit if you want to explore prediction markets conceptually without touching crypto. Gnosis provides the underlying conditional token framework that powers several prediction market experiments and is worth knowing if you are building rather than using.
None of those alternatives offer Augur's self-hosted, fully local approach. If running your own node is a requirement — for privacy, for data access, or on principle — there is no direct substitute.
How does Augur compare to Polymarket?
Polymarket wins on usability and liquidity in 2024: it runs in any browser, markets resolve quickly, and the active trading community means tighter spreads. Augur wins on decentralisation and self-custody: your node, your keys, no company between you and the chain. Polymarket is the choice for traders; Augur is the choice for operators who want full control over their stack. The two audiences barely overlap.
