In case you didn’t know, there’s a whole world of useful and interesting crypto-related tools available for everyone; beyond crypto networks themselves and dedicated wallets. Some of them are paid, most of them are free, and some more are open-source and free. That means anyone can check and even copy their codes from a public code-hosting platform like GitHub.

On the latter website, we can find applications like portfolios, price alert systems, Telegram bots, tax helpers, and much more. You can use these tools for free now and likely forever. However, if you want to support their development long-term, consider making a crypto donation via Kivach. This is an Obyte-based cascading donations platform where you can send different crypto coins to literally any public GitHub repository. Developers don’t even need to know from the onset that you’re donating!

Now, let’s explore some free crypto tools you may like to discover.\

Rotki

Rotki is a privacy-first app that helps you track your crypto assets, without handing over your financial data to some company. It was launched in 2018 by developer Lefteris Karapetsas, who wanted a safer, open-source alternative to those sleek but data-hungry portfolio trackers. With Rotki, everything is stored locally on your device, encrypted and away from prying eyes. Think of it as a finance journal that lives on your computer, not the cloud.

Once you set it up, Rotki gives you a full view of your net worth across different exchanges, wallets, and even DeFi protocols. It breaks down every transaction so you actually understand what happened. You can customize reports, see how your assets are growing (or shrinking), and even get profit/loss summaries. It works on Windows, macOS, and Linux, and there’s a free version with plenty of features to get started.

Rotki stays alive thanks to its community. No big backers, just users donating crypto or subscribing for extras. If you like the idea of managing your money without giving up privacy, Rotki is definitely worth checking out. If you want to donate some crypto to these developers, find them on Kivach as rotki/rotki.

My Coins Alert

This is a handy Telegram bot created in 2024 by developer Khun Htetz Naing. It’s designed for crypto fans who want to keep an eye on prices without staring at charts all day. Whether you’re a seasoned trader or just watching the market casually, this bot helps by sending you a quick Telegram message the moment a coin hits the price you’re waiting for. It’s like having a tiny assistant who watches the markets for you, so you can relax or do anything else.

What makes My Coins Alert so convenient is how simple it is to use. You just type a command like /alert BTC > 100000 and that’s it. You’ll get a ping if Bitcoin climbs above $100k. You can also track multiple coins, set alerts for prices going up or down, and remove or check your alerts with a few short commands. Everything runs smoothly inside Telegram, so there’s no need to install extra apps or log into exchanges. It runs on Python and keeps only the info it needs. Your alert settings stay private and are never shared.

You won’t see a company name behind this project, just a GitHub repo where anyone can suggest features or help improve the code. There’s no flashy subscription model either; it’s completely free to use. If you’re into supporting small, useful tools that respect your privacy, this is one to check out —and maybe even contribute to if you’re feeling generous. It appears on Kivach as khunhtetznaing/mycoinsalert.\

Freqtrade

Let’s turn up the complexity a bit with this one. This is a cryptocurrency trading bot launched in 2017 by developer Michael Egger and is now maintained by a contributor named xmatthias. It lets you automate trading on major exchanges like Binance or Bybit without needing to sit at your computer all day. The program will follow your trading rules, buying and selling crypto based on strategies you set up.

Freqtrade comes packed with useful tools like backtesting (testing strategies on past market data), dry runs (simulating trades without real money), and even machine learning to optimize your approach. You can control it via a simple web interface or Telegram. A basic strategy might involve indicators like RSI (Relative Strength Index) to decide when to buy or sell. However, remember that trading always carries risks: markets move fast, and even the smartest bots can’t guarantee profits. That’s why the team encourages starting with simulations and understanding how everything works before diving in.

As an open-source project, Freqtrade thrives on community contributions. Developers and traders chip in by improving code, documenting features, or testing exchanges. There’s no corporate funding, just passionate volunteers and users helping each other on social media. If you’re curious, you can join the community, tweak the bot (Python knowledge helps!), or even just explore its features risk-free. Of course, you can also donate crypto to them via Kivach.

Raccoin

Released in 2023 by developer Thorbjørn Lindeijer, Raccoin is designed for anyone trying to stay on top of their crypto investments—especially when it comes to taxes. If you’ve ever panicked at tax season trying to figure out what you earned (or lost!) trading crypto, this handy little app is here to help. It gives you a clear view of your crypto portfolio over time and creates detailed reports that make declaring capital gains in euros a lot easier.

The software works with a wide range of wallet and exchange exports, like Binance, Electrum, Trezor, and even defunct platforms like FTX. It also supports direct blockchain syncing for Bitcoin, Ethereum, and Stellar, though adding those wallets still requires a bit of manual setup. Under the hood, it’s built with Rust (a fast, modern programming language) and uses Slint for its interface. You don’t need to be a techie to use it, but if you are, you can add other currencies and accounting methods beyond EUR and FIFO.

As an open-source and free tool, Raccoin is maintained by its creator, community contributors, and users who care. If you find it useful, you can support it by pitching in code, suggesting improvements, spreading the word, or donating. The project is on Kivach as bjorn/raccoin.\

ZeroNet

We've already seen tools that work for managing cryptocurrencies, now we'll look at a tool that works thanks to crypto. ZeroNet is a peer-to-peer platform launched in 2015 by Hungarian developer Tamas Kocsis, and its main purpose is to let you create and browse websites that don't rely on a central server. Instead, these sites (often called zites by users) are shared directly between visitors.

This makes ZeroNet especially appealing to people who care about freedom of speech and online privacy, or just want to explore an alternative web that’s basically uncensorable because of its underlying tech. Behind the scenes, it borrows cryptographic tools from Bitcoin to identify and protect site owners, and it taps into the BitTorrent network to share content between users.

When you visit a site, you start "seeding" it to others, just like when you're sharing a torrent. There's no need to set up a server or pay for hosting since your visitors help keep your site alive. And thanks to support from the Tor network, you can even stay anonymous while doing all this.

As for funding, ZeroNet has relied mainly on individual donations. Supporters have contributed through Bitcoin or PayPal. This is truly a grassroots effort, kept alive by an open-source community that believes in an uncensored, decentralized Internet. If you’re interested in supporting them, remember that you can contribute crypto via Kivach.

Send and Receive Donations with Kivach

If you’d like to support a project on GitHub using crypto, Kivach makes it surprisingly easy. First, you'll need an Obyte wallet, which you can top up by exchanging popular tokens like ETH, USDC, or WBTC for GBYTE (Obyte’s native currency). It’s possible to donate with several tokens, but GBYTE will work for small transaction fees.

Once you’ve got that sorted, just head to the Kivach website, search for the GitHub repo you want to support, pick your donation amount and preferred token, and send it off. You don’t need to worry whether the developer has already set up their account because your donation will wait patiently until they claim it. The cool part? If they’ve enabled “cascading donations,” a portion of your gift could ripple out to other projects that made theirs possible.

If you’re a developer hoping to receive crypto contributions through Kivach, the process is just as friendly. After installing the Obyte wallet, you’ll use a GitHub Attestation bot to link your account and confirm ownership of your repo. Once that’s done, you’ll be able to set donation distribution rules: choosing whether to keep everything or share some with other open-source projects you rely on. You can claim any past donations too, even if you weren’t set up earlier. It’s a great way to earn support and pay it forward at the same time.
