Cycling through all six. Tap any point to stop.

Measured on six things

Portfolio optimization and risk metrics for investors.

Growth

Real problem (scattered risk metrics), specific wedge (free institutional-grade analytics plus public portfolio cloning) against Portfolio Visualizer, Sharesight and Morningstar. Category has headroom, but the sharing/community angle is the only thing incumbents can't trivially copy.

Scout Review

Written by AI from measured evidence, scored out of 100.

Redstone is a cloud portfolio analytics platform that puts quant-grade risk metrics — Sharpe, Sortino, Alpha, Beta, Calmar, Omega, Martin — in front of everyday investors at a free tier that actually includes them. The measured evidence backs up the pitch: Lighthouse mobile performance 98/100 with zero layout shift, a full security-header stack with SPF and DMARC, and an accessibility audit at 95/100 with two fixable failures. The product's real differentiator is the combination of free institutional metrics with public portfolio cloning and sharing, which none of its listed alternatives — Portfolio Visualizer, Sharesight, Morningstar — offers in the same shape. Where it falls short is the softer stuff: placeholder-feeling testimonials, no visible documentation or help center, no published compliance certifications, and a community that is currently a seed rather than a network. For a DIY investor or finance student who wants to see their Sharpe ratio without paying Morningstar, Redstone is a genuinely good deal today. For an institution or anyone who needs audit-grade assurances, it isn't there yet.

Measure by measure

Usability

Free tier includes every chart and risk metric plus screeners, and the public compare tool works without an account — near-zero time to value. Pricing matrix is clear. Docs/help center depth isn't visible from the fetched pages.

Design

Dense but coherent data-first UI: real dashboard screenshots on the landing page, consistent numeric typography, and a live MAG7 table showing Sharpe, Max DD and Alpha. Placeholder-looking testimonials and a competitor name-drop in one quote drag it down.

Speed

Lighthouse mobile 98/100 (LCP 2.0s, CLS 0, TBT 134ms) and desktop 100/100. Zero layout shift and 1.2s FCP point to a lean, well-optimized front end — clearly ahead of typical finance dashboards.

Security

Full security-header stack verified (HSTS, CSP, frame protection, Referrer-Policy, Permissions-Policy) plus SPF and DMARC — 12/12 on the probe. No published SOC 2, ISO, pen-test or bug-bounty program found, which caps it below the top of the band.

Accessibility

Lighthouse a11y 95/100, but two real failures: insufficient color contrast and non-sequential heading order. No WCAG statement or multi-language support found. Solid automated baseline, held back by the contrast issue on a data-dense UI.

Design & Usability

Redstone's design is unapologetically data-first, and that works in its favor: the landing page leads with an actual MAG7 portfolio table showing Sharpe, Max Drawdown and Alpha, so visitors see the product before they see marketing copy. Typography and spacing are disciplined, and the dark-on-light numeric styling reads as competent rather than templated. The weak spot is social proof — testimonials with generic names, one of which name-drops a competitor, undercut the polish. Usability is where the product earns its keep: the free Starter tier includes every chart and risk metric, both screeners, and daily updates, and the public 'compare any stock vs any ETF' tool works without an account. That is a genuinely low-friction path to value. The pricing matrix is clear and the monthly/yearly toggle is honest about the 17% saving. What we couldn't verify is documentation depth — no help center or docs page surfaced in the fetched content, which matters for a tool aimed partly at finance students.

Speed & Security

Speed is the standout measured result: Lighthouse mobile 98/100 with LCP 2.0s, CLS 0 and TBT 134ms, and a perfect 100 on desktop. A cumulative layout shift of zero on a page this dense with tables and charts is not accidental — it points to a lean, well-engineered front end, likely static or edge-served. For a finance dashboard that users will refresh repeatedly during market hours, that snappiness is a real product advantage, not just a vanity metric. Security is solid on the transport and header layer: HTTPS enforced, HSTS, CSP, frame protection, X-Content-Type-Options, Referrer-Policy and Permissions-Policy all present, plus SPF and DMARC configured — 12/12 on our probe. What's missing is the compliance layer: no SOC 2, ISO 27001, published penetration test or bug-bounty program was found. For a tool holding portfolio data (not funds, but still personal financial information), that's a reasonable gap at this stage but a clear ceiling on the score.

Accessibility & Growth

Accessibility lands at a solid-but-imperfect 79. The automated audit scores 95/100, but two failures are real and relevant: insufficient color contrast and non-sequential heading order. On a product whose core value is reading colored numeric tables, contrast is not a cosmetic issue — it's the primary interface. No WCAG conformance statement or multi-language support was found, which keeps it out of the top band. Growth is the most interesting dimension. The problem Redstone names is real: DIY investors genuinely scatter performance and risk data across broker apps, spreadsheets and free calculators. The wedge is specific — institutional-grade metrics (Sharpe, Sortino, Alpha, Beta, Calmar, Omega, Martin) on a free tier, plus public portfolio cloning and sharing that Portfolio Visualizer, Sharesight and Morningstar don't offer in the same shape. Morningstar owns research, Sharesight owns tax reporting, Portfolio Visualizer owns backtesting; Redstone's bet is that a fast, free, shareable risk dashboard is the missing middle. The limit is that the community angle is thin — the site claims 50+ user portfolios, which is a seed, not a network. If sharing compounds, the moat grows; if it doesn't, this is a nicer UI on a solved problem.

Conclusion

The honest verdict: Redstone is a well-built, fast, free-to-start analytics tool with a clear niche and a real technical foundation. It is not trying to beat Morningstar at research or Sharesight at tax reporting — it is trying to be the fastest way to see whether your portfolio's returns are actually worth the risk you're taking. On that narrow question, the evidence says it delivers. The next twelve months will decide whether the community and sharing features turn into a moat or stay a nice-to-have. Until then, it's a strong pick for self-directed investors and students, and a watch-list item for anyone who needs compliance paperwork before they'll trust a dashboard with their holdings.

Suggestions for improvement

Replace the generic testimonials with real, attributable user quotes or remove them — the PortfolioLab name-drop reads as placeholder.
Publish a help center or docs section explaining each metric (Alpha, Omega, Martin) so students can actually learn from the tool.
Fix the two Lighthouse a11y failures: raise contrast on colored table text and correct heading hierarchy.
Add a security/compliance page stating data handling, and pursue at least a self-attestation or SOC 2 roadmap.
