If you have a Zerodha account, try Streak first. It is free for Zerodha customers, it gives unlimited equity backtests, and no honest comparison can start anywhere else. The rest of this page is about what the others give you, and where the free tiers stop.
"Free" is the most searched word in this category, and most of what it attaches to is a trial rather than a tier. The difference matters: a trial ends, a tier does not.
What each platform gives away
| Platform | Free tier | Price |
|---|---|---|
| Streak | Free for all Zerodha customers, with unlimited equity backtestsZerodha Z-Connect, 17 Jan 2024 | Not publishedThird-party reviews say Rs 350 to Rs 1,400 a month. Zerodha's own post says free for their customers, and streak.tech carries no public pricing page at all - checked by hand on 9 Sep. Two sources disagree and neither is checkable, so we publish no price for Streak. |
| AlgoTest | Not publishedTheir blog says 25 backtests a week, permanent. Their own pricing page shows no free tier at all on any of its four tabs. Withheld until one of them is confirmed by signing up. | Backtesting is sold as a window, not a subscription: Rs 599 for 7 days, Rs 1,499 for 30, Rs 3,499 for 90, Rs 5,999 for 180, all with unlimited runs inside it. Or 1 credit per backtest with no expiry. Their Rs 499 a month plan is ClickTrade, which is live tradingAlgoTest's own pricing page, 9 Sept 2026 |
| StockMock | Not publishedNo free tier appears on their plans page. Absence on a page is not proof, so not published. | Two separate products. Analytics, meaning the simulator, builder and charts: Rs 349 for 30 days, Rs 1,599 for 180, Rs 2,599 for 360. Backtesting is its own window: Rs 449 for 7 days, Rs 1,299 for 28, Rs 2,999 for 84. All plus 18% GSTStockMock's own plans page, 9 Sept 2026 |
| Tradetron | Not checked | Not publishedWithheld 10 Sep under the owner's sourcing rule: a competitor claim is published only when a reader can click through to that competitor's OWN page and check it. The only source we hold is AlgoTest's blog writing about a rival, which lands the reader on a competitor's marketing rather than on the company being described. Unblock it by reading the figure from their own pricing page. |
Read the withheld cells rather than skipping them. AlgoTest's own blog says they have a permanent free tier of 25 backtests a week. Their pricing page, which has four separate tabs, shows no free tier on any of them. We could not reconcile those two, so we publish neither. StockMock's plans page shows no free tier either, and absence on a page is not proof of absence, so that is withheld too rather than stated as a fact.
That is the honest state of free backtesting in India: one platform gives it away properly, two are unclear, and most of the rest sell it in windows.
The thing most comparisons get wrong about "unlimited"
Both AlgoTest and StockMock sell unlimited backtesting inside a window you rent. You buy seven days, or twenty-eight, and inside that period you can run as many as you like. StockMock's version carries a fair-usage note about hourly and daily limits on top.
That is a genuinely reasonable model and it is not the same thing as a free tier. It means the question is not "how many backtests do I get" but "how long do I have", and if you test in bursts it may suit you better than a subscription.
Where the free tiers actually stop
Ours stops on the data: Unlimited backtests on the free plan. What Free limits is DATA - three years, the Nifty 50, no options - never the number of runs
That was a deliberate decision rather than generosity. A free backtest costs us a fraction of a rupee to serve, so capping the count would have been theatre. What a free account does not get is the full history, every listed company, or options. The pricing page has the exact split.
And the whole market-data surface is free with no account at all: the option chain, max pain and PCR for five indices, every F&O stock with its own page, and the plain English screener.
Where the others are better than us
Streak is free for Zerodha customers and it deploys live, placing real orders. EdgeTest is analysis only and does not trade at all. For a Zerodha customer who wants to go from idea to live order in one product, that is not a close call.
AlgoTest is intraday-first across every underlying. Our options engine checks its rules once a day on the settle price, except on one index.
StockMock has deeper expiry-day tooling than we do.
Is there any genuinely free backtesting in India?
Yes. Streak is free for Zerodha customers with unlimited equity backtests, and EdgeTest's free plan has no cap on the number of backtests either. Both limit something else instead: Streak on history depth and options runs per day, EdgeTest on how far back you can go and which companies you can test.
What is the catch with a free backtesting tier?
Usually the data. Free tiers are rarely limited by how many tests you run, because a backtest costs the provider very little. They are limited by how far back you can test, which companies are included, and whether options are covered at all. Those three limits decide what a backtest can actually tell you.
Do I need an account to see the market data?
Not on this site. The option chain, max pain, put-call ratio, implied against realized volatility, delivery percentage and the screener are all open with no sign-up. An account is only needed to run a backtest and keep the result.
Is a free backtest worth anything?
It is worth exactly as much as the data behind it. A free backtest over three years of large-cap history is a real answer to a narrow question, and it cannot tell you what your rule does in a crash, because there has not been one in that window. That is the honest limit and it applies to every free tier here, ours included.
