Its site carried a banner on 2026-09-17 warning of downtime during a data-pipeline rebuild, and several of its own listed routes returned 'Trader not found' at fetch time. 0xinsider is a paid, sports-and-esports-only product with a published grade and eligibility floors. ## Highlights | Metric | 0xinsider | PredictFolio | Winner | | --- | --- | --- | --- | | Cost | Free account plus a paid Pro tier | Completely free, including the API | PredictFolio | | Trader scoring | Published grade with eligibility floors | smartScore (0-100); method not published, plus a like/dislike popularity vote | 0xinsider | | Multi-account portfolio view | Not offered | Combined activity feed and top wins across linked accounts | PredictFolio | | API commercial use | Permitted under a Pro subscription | Licensed CC BY-NC 4.0: personal and academic use only | 0xinsider | ## Comparison | Feature | 0xinsider | PredictFolio | Winner | | --- | --- | --- | --- | | Type | Prediction-market analytics for sports and esports | Free Polymarket trader-analytics and P&L tool | -- | | Platforms covered | Polymarket | Polymarket | Tie | | Cost | Free account, Pro subscription for live data | Free, including the API for personal and academic use | PredictFolio | | Trader scoring | 0-100 grade, F-to-S, with eligibility floors above C | smartScore (0-100, composite); method not published. A separate 'Profile score' is a like/dislike popularity vote, not a skill measure | 0xinsider | | P&L decomposition | Realized profit with maker and taker rebates credited, fees included | Explicit lines for profit after fees and rebates, and a separate figure adding LP, holding, and Merkle-claim rewards | -- | | Multi-account view | Not offered | Combined (multi-account) activity feed and top-wins view, with an ADD ACCOUNT / COMPARE tool | PredictFolio | | API license | Usable in a commercial product under an active Pro subscription | CC BY-NC 4.0: personal, academic, and non-commercial use only | 0xinsider | | Site status observed 2026-09-17 | Fully live | Site-wide banner warns of a data-pipeline rebuild; /dashboard, /news, /blog, /traders, and /polyalpha all returned 'Trader not found' at fetch time | 0xinsider | | Sports and esports focus | Dedicated boards and in-play tracking | All Polymarket categories, no sports-specific view | 0xinsider | ## What PredictFolio is, and what we found on 2026-09-17 PredictFolio's footer calls it 'a free to use tool that leverages blockchain data to provide insights into prediction market traders' performance,' and its terms of service name ClearCode B.V., based in the Netherlands, as the operating company. A site-wide banner on 2026-09-17 read: 'We're rebuilding our data pipeline for real-time data. You may see some downtime over the next few days.' Consistent with that, several routes its own sitemap lists (/dashboard, /news, /blog, /traders, /polyalpha) returned 'Trader not found' at fetch time, and /community showed 'Coming soon.' ## Cost and access PredictFolio is entirely free. No paid plan was found anywhere on the site, including for its API, which serves an OpenAPI 3.1 specification with 44 documented paths. 0xinsider's core reads are free with an account, but the live feed and full analytics require a paid Pro subscription. **Verdict (PredictFolio):** Free beats a subscription, for a reader who only needs the free feature set. ## Trader scoring and P&L accounting PredictFolio's leaderboard sorts by a smartScore, described only as 'Composite score (0-100)' with no published method. A separate 'Profile score' is explicitly a popularity metric: 'based on total amount of likes and dislikes,' not a skill measure. Where it goes further than most competitors here is P&L transparency: its bundle describes 'profit after trading costs: mark-to-market PnL minus fees paid, plus rebates earned,' as a distinct figure from a second number that adds LP, holding, and Merkle-claim rewards on top. 0xinsider's grade is about 95% realized (banked) profit, with eligibility floors that do real work: anything above a C needs verified net-positive realized profit, and the top three grades also need a real resolved-market count and a survivable worst drawdown. Its own P&L accounting credits maker and taker rebates and includes fees, though it does not break the figure into as many separately named lines as PredictFolio's profile page does. **Verdict (0xinsider):** A published grade beats an unpublished score, though PredictFolio's P&L breakdown is genuinely more granular. ## Multi-account views and the API license PredictFolio lets a reader add and compare several wallets in one view, with a combined activity feed and combined top-wins list across every linked account. 0xinsider has no equivalent: each grade and profile is a single wallet. The tradeoff sits in the API license. PredictFolio's API is 'provided for personal, academic, and non-commercial use only' under CC BY-NC 4.0, which rules out building a commercial product on it. 0xinsider's API and MCP server are usable in a reader's own commercial tools and agents under an active Pro subscription. **Verdict (PredictFolio):** Multi-account views are a real PredictFolio strength; its API license is a real limit on what you can build with it. ## What each one costs PredictFolio is free, with no paid plan found for any feature, including the API. 0xinsider's free account includes the full trader leaderboard, full trader profiles with Insights, the previous day's large trades, and one Pick of the Day. Pro adds the live large-trade feed, custom alerts, Insider Radar, the REST API and MCP server, and in-game position changes while a game is live. Current plans are on the [pricing page](https://0xinsider.com/pricing). ## Which one to use Use PredictFolio if the job is free, all-category Polymarket reads with a detailed fee-and-rebate P&L breakdown and a multi-account view, and the current rebuild-related downtime is one you can work around. Use 0xinsider if the job is a sports and esports grade with published eligibility floors, an API you can build a commercial product on, and a site with no active rebuild notice. ## Best for 0xinsider - Traders who want a published grade with eligibility floors instead of an unpublished smartScore - Developers who need to use the API in a commercial product, not just personally or academically - Sports and esports traders who want a dedicated board, not an all-category tracker ## Best for PredictFolio - Readers who want every feature free, with no subscription - Traders who track more than one account and want a combined multi-account view - Anyone who wants a fee, rebate, and reward P&L breakdown by name on the profile page ## 0xinsider: Pros & Cons **Pros** - Published grade with eligibility floors, not an unpublished score or a popularity vote - API usable in a commercial product under a paid subscription - Sports and esports focus with dedicated boards - No active rebuild notice or broken routes at time of writing **Cons** - Costs a subscription; PredictFolio is free - No multi-account consolidated view - P&L is not broken into as many separately named lines as PredictFolio's ## PredictFolio: Pros & Cons **Pros** - Completely free, including the API - Combined multi-account views and a compare tool - Explicit fee, rebate, and reward breakdown on the P&L figure - 44-path OpenAPI specification published for the data **Cons** - The smartScore's method is not published - The API license (CC BY-NC 4.0) rules out commercial use - Several routes (/dashboard, /news, /blog, /traders, /polyalpha) returned 'Trader not found' on 2026-09-17, alongside a banner warning of a data-pipeline rebuild - Some documented endpoints declare Bearer JWT auth but responded without a token when checked
