Our Take
Portfolio123: Portfolio123 is the most powerful quantitative screening and backtesting platform available to retail investors. Its combination of institutional-grade FactSet data, 20-year point-in-time backtesting, multi-factor ranking systems, and commission-free broker integration creates genuine analytical depth that no consumer alternative matches. The learning curve is steep and the interface is dated, but for systematic investors willing to invest the time, no other platform delivers this level of quantitative rigor at $25-83/month.
Sharesight: Sharesight is the strongest portfolio tracker available for dividend investors and international portfolios. Its automated trade imports, multi-currency performance calculations, and jurisdiction-specific tax reports eliminate the spreadsheet burden that plagues self-directed investors managing holdings across multiple brokers and countries. The interface is clean, the reporting is deep, and the free tier is genuinely useful for small portfolios. It falls short on alternative assets and active trading use cases, but for buy-and-hold investors who need accurate performance and tax data, no single competitor delivers this combination at this price point.
Pricing Comparison
Portfolio123 Pricing
Portfolio123's pricing is straightforward and competitive for the depth of tooling it provides. The free tier includes broker integration with Tradier and Interactive Brokers, fundamental charting, and a consolidated brokerage account view — useful but limited for research. The Screener plan at $25/month unlocks the full financial database, 460-plus screening metrics, and five years of backtesting data. The Pro plan at $83/month adds 20 years of backtesting, multi-factor ranking systems, rolling screens, position sizing, and API access. Annual billing saves 28% on Retail plans and 23% on Pro plans. A 21-day trial at $19 provides full Pro-level access with 10 years of data and no auto-renewal — a low-risk way to evaluate the platform. For context, Stock Rover Premium Plus costs $28/month with shallower backtesting, while Trade Ideas starts at $118/month for a narrower use case.
Sharesight Pricing
Sharesight's freemium model provides a genuinely functional free tier — 10 holdings, one portfolio, and access to core performance tracking. For index fund investors holding a handful of ETFs, the free plan may be sufficient indefinitely. Beyond that, paid plans scale by holdings and portfolios: Starter ($9.33/month or $7/month annually) covers 30 holdings; Standard ($24/month or $18/month annually) unlocks unlimited holdings, four portfolios, and advanced tax and diversity reports; Premium ($31/month or $23.25/month annually) adds 10 portfolios, 10 custom groups, and priority support. Annual billing saves roughly 25%. A Business plan at $13.50 per portfolio per month serves accountants and advisors. Compared to competitors, Sharesight sits in the mid-range — more expensive than free alternatives like Empower, but cheaper than Kubera's $249/year for a single-purpose net worth tracker. The key value inflection is the Standard plan, where unlimited holdings and tax reports unlock the platform's core differentiation.
What Users Say
Portfolio123
User sentiment is overwhelmingly positive among those who invest the time to learn the platform. On Trustpilot (4.8/5, 50 reviews), 88% of ratings are five stars — an unusually high concentration. Users describe it as "the best quant platform for retail users" and "simply the best product for quantitative stock analysis." Several long-term members report that Portfolio123 "genuinely changed my life as an investor," citing the shift from intuition-based to systematic, data-driven decision-making. Professional reviewers at GreatWorkLife and LiberatedStockTrader both award 4.1/5, praising screening depth and backtesting power while noting the learning curve. The sole recurring negative theme is the steep onboarding — not the platform's capability or value. One Trustpilot reviewer gave a single star citing community dynamics, but this is an extreme outlier against 49 four- and five-star ratings.
Sharesight
User sentiment toward Sharesight is positive overall, with particularly strong endorsement from Australian and New Zealand investors. On Trustpilot (4.0/5, 541 reviews), 68% of ratings are five stars, with users praising responsive customer support and time saved on tax preparation — one reviewer called it "the best share software in NZ and Australia." ProductReview.com.au (4.0/5, 150 reviews) echoes this, with users highlighting accurate CGT reports and easy broker auto-imports. Benzinga rates the platform 4.5/5. The negative themes are consistent across platforms: pricing feels steep for smaller investors, the no-refund policy on annual plans frustrates some users, and the mobile apps lag behind the web experience. Capterra (3.3/5, 3 reviews) shows a notably lower score, though the tiny sample size limits its significance. The value-for-money rating of 2.5/5 on Capterra reflects a recurring concern — Sharesight delivers excellent functionality, but investors with smaller portfolios question whether the cost is proportional to the benefit.
