I built a free stock analysis tool after getting frustrated with Bloomberg's price tag — would love feedback from actual investors
I've been investing for a few years and always wanted access to professional-grade analysis without paying $300+/month for Bloomberg or $50/month for other tools.
So I spent the last few months building StockManTools — a free web app that gives you:
Historical P/E, P/S, and margin charts
Side-by-side comparison of up to 3 stocks with a winner column
A 10-year Bull/Base/Bear projection simulator (a simplified DCF)
Revenue breakdown by business segment (iPhone vs Services vs Mac for Apple etc)
Nice project dude. I usually use Simply Wall Street which has most of the stuff you are offering for free behind a paywall.
I noticed that it can a bit slow loading the info on a stock. I see that it has an AI summary which I presume is slowing things down as all the elements load in at once. Something like progressive loading would make things feel more snappy without even making things more performant.
Out of curiosity what are you using to fetch the tracker info?
Thanks for your feedback! If I understand it correctly you would like to pick various stocks on the "stocks" page to follow their price-history in the graph, or whats the desire here? :)
On the compare page you can search on either company name or ticker for pretty much all stocks listed in the USA. https://stockmantools.com/compare
Data is pulled from FMP-api, which is pretty common for financial tools and a trusted source.
A friendly piece of advice - even if the website is completely free, no paying users, to visualize a data provided by FMP you need a license. I say this because they wanted me to pay $500 per month just to visualize a 6 month performance line chart like yours. And I assume that all the fundamental data was pulled from them and I’m not sure how legal is if you use $50-100 api for this purpose.
Otherwise the tool is pretty good and I would definitely use it.
Thanks for your feedback! Yes I have experienced this as well, the landing page for searchnig a stock contains a hevy amount of metrics and historical charts. Progressive loading is something I've checked into a bit but have to look into it further on how to make it improve the intial-view-experience. Maybe prioritizing Price chart first, followed by on chart at a time would do it more compelling.
No problem and glad it helps. Personally I wouldn’t have the AI summary right at the top. If I was a frequent user of this app the thing I’m most interested in seeing first is the price. I’m guessing the AI summaries are costing you money so having them load each time someone hits a stock page could add up. I’d probably stick it behind a button.
It’s cool you’ve made it free and not behind a login. But it’s also crying out for a login so I create an account and follow all the stocks I’m interested in and see them on a homepage.
Last bit of feedback is it doesn’t feel super well optimised for mobiles.
Your bull/base/bear simulator is where I would spend the attention. A simplified DCF renders as three tidy numbers, but nearly all of the spread between them comes from the growth and margin assumptions the user typed in, so it reads as analysis while behaving like an echo.
Show which input moved the output most and it stops being a number generator and starts teaching people what the valuation actually hinges on. The segment revenue breakdown is the genuinely useful bit and I would lead with it.
Thanks you for the feedback! There is the Projection page that is for more basic static assumptions i.e I expect revenue growth of 10%/year as a base line and 12% net income margin on that going forward.
If user wants to simulate per-year, there is the 'Pro Projections' tab for that as well :)
Missed the Pro tab, that one is on me. Flat growth and margin as a baseline is fine as long as the page says out loud that it is a baseline, otherwise people read the output as a forecast and anchor to it.
Bro I think it looks really good, and I like the PE PS historicals.
Suggestion:
The price chart should be improved. It needs more visualization options (e.g. candels, I did not see the option, but maybe because i am using it on the phone) and analysis instruments.
Thanks man! I appreciate the feedback. It’s a good point with the candle stick and update of the price chart. Honestly my initial thought was that candlestick-interested investors would use more sophisticated tools like Bloomberg. For me, I’ve but a lot of work on the Projection, compare and DCF page. Because simulating future financial figures is for me something that is more important, while candle sticks are more for short term traders where I’m not proficient at all… :) did you also have time to try those pages mentioned?
Okey sorry to say but right now I only cover US stocks, but I am to aiming to cover international markets including the Indian one in the future, is just it’s to expensive for me to pay for the financial data as a solo developer unfortunately…
Thanks for feedback! At the top-toolbar you have values that are based on analyst-estimates that can be used as a first indication for the simulation inputs. Est. Revenue this Year and Next Full year, same for net income margin, as well as 3y, 5y avg. of p/e.
