Savemyeosram is a free, open-source tool for developers who create token contracts on the EOS blockchain and want to control the RAM those contracts consume. It is built on Node.js and targets a cost that catches many EOS builders off guard: the memory an account must reserve when a token contract is stored. If you are searching for Savemyeosram for Windows, this page explains what the program does, how to install it, and what to watch for.
Read the project status before you install anything. The last code update was on July 8, 2018, and the project is no longer maintained. Its latest listed version is v1.0. Windows is mentioned in the documentation, but Windows support remains unverified, so treat the program as a reference for learning rather than a tool you rely on in production.
What Is RAM on EOS and Why It Matters
RAM on EOS works differently from the gas model many developers know from Ethereum. An account must reserve RAM to store its data, and that includes the code and tables of a deployed contract. Because RAM is limited and traded in a market, its price in EOS per kilobyte changes over time.
The project's author pointed to this cost directly. At a price of 0.45 EOS per KB, they estimated that a typical test token could occupy roughly 190 KB, which turns a small experiment into a noticeable expense. That gap is what Savemyeosram was written to address. The figures reflect the time the tool was written, so treat them as an illustration of the mechanism rather than a current price.
Who Savemyeosram Is For
Savemyeosram suits a narrow group of people: developers and students who create tokens on EOS and want to see how RAM use adds up. Picture a student who deploys several test tokens to learn the eosio.token contract. Without measuring, each test can quietly consume RAM the student must buy. A tool focused on RAM gives that person a concrete number to watch.
It is less suited to teams that need a current, supported toolchain. Because the project has had no code updates since 2018, a production team would have to review and maintain the code itself. Anyone who wants a broader EOS workflow should treat this tool as one small part of the setup, not the whole environment.
How to Read RAM Figures Before Deploying a Token
The project's example records RAM usage before and after a contract was set: 39,547 against a total of 600,186, then 7,918 against the same total. Reading these numbers starts with the total, because the used figure only means something relative to what the account holds. Comparing the before and after values shows how much the contract itself consumed.
When you test, record each figure alongside the step that produced it. A simple log with the contract version, the RAM used, and the remaining total is enough. Repeating the same measurement after each change shows which edit made a difference, and that is more useful than a single snapshot because RAM use depends on what a contract stores and how it is written.

How to install Savemyeosram on Windows
- 1
Install Node.js
Go to the official Node.js website and download the installer for Windows. Always download only from the official website. The original author developed with Node.js 9.11.1 and noted that 8.x and the 10.x line should also work in theory, so pick a version within that range if you want to match the documented setup.
- 2
Get the Source Code
Open the project's GitHub repository at github.com/breakstring/savemyeosram. You can download the source as a ZIP archive or clone it with Git. The archive is the simplest choice for a one-time setup.
- 3
Extract the Files
If you downloaded an archive, extract it to a folder you can easily find, such as a folder in your user directory. Keep the project files together so the next step runs in the correct location.
- 4
Open a Terminal in the Project Folder
Open Command Prompt or PowerShell and navigate to the root folder of the project. The root is the folder that contains the project's main files, not a subfolder.
-
Run npm install
Type npm install and press Enter. This command installs the bundled libraries the tool needs. Wait for the process to finish and check the output for errors before moving on.
System requirements
- Windows, as mentioned in the project documentation; Windows support has not been verified
- Node.js, with the author using version 9.11.1 and noting that 8.x and 10.x should work in theory
- npm, which comes with Node.js and installs the project's libraries
- Command Prompt or PowerShell for running npm install
How to use Savemyeosram
Savemyeosram works from the terminal after its libraries are installed. Use the steps below to set it up and read its output carefully, since the project has not been updated in years.
- Finish the npm install in the project folder and confirm that no errors appeared.
- Read the project documentation and the example RAM figures to understand what the tool measures. The original text is in Chinese, so a translation tool may help.
- Set up a test environment, such as a non-production EOS account, before you touch anything that holds real funds.
- Deploy your test token contract in that environment and note the RAM usage before and after the contract is set.
- Compare the figures against the total RAM available to your account to see how much space the contract used.
- Keep a log of each test so you can repeat the same measurement after changing your contract.
- Cross-check any result against a current tool before relying on it, because the code has not received updates since 2018.
Pros & cons
- Free to download and use
- Open-source code published on GitHub for review
- Narrow focus on the RAM cost of EOS token contracts
- Simple dependency setup with npm
- Includes concrete RAM figures that help illustrate the cost
- No code updates since July 2018, so the project is no longer maintained
- Windows support is mentioned but unverified
- Requires Node.js and a terminal, which may be unfamiliar to some users
- Original documentation is in Chinese
- Only one version, v1.0, is listed
Is Savemyeosram safe?
Savemyeosram has not been updated since July 2018, so treat it as an older, unmaintained project. Download only from the official website or the project's GitHub repository, and compare the file's SHA-256 checksum or signature if the publisher supplies one, so you know the file was not altered. Read the code before running it, and be cautious with dependencies that were current in 2018 but may now have known issues. Never paste private keys, seed phrases or account credentials into a website or third-party tool. Test on a non-production setup before using the tool with any account that holds funds. Check the latest version on the official website before you begin.
- Official source only. Download from github.com/breakstring/savemyeosram. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Savemyeosram is narrow. It targets the RAM cost of EOS token contracts, while the other tools on this catalog cover broader workflows. Remix Desktop is an IDE for Solidity, and Foundry gives you forge, cast and anvil for smart contract work. Tenderly CLI focuses on debugging and monitoring contracts, and Anchor is a framework for building secure Solana programs. Visual Studio Code with Solidity extensions is an editor for smart contract projects. If your work centers on EVM contracts or general testing, those tools cover more ground. Savemyeosram makes most sense when EOS RAM costs are your specific concern, and given its age, it is best used as a learning reference.

Frequently asked questions
Savemyeosram is free and open source, but it has had no code updates since July 2018, so it carries more risk than actively maintained tools. Use the copy from the GitHub repository, review the code, and test in a non-production setup first. Never share private keys or seed phrases with the tool or with any website.
Savemyeosram is used to explore and reduce the RAM cost of token contracts on the EOS blockchain. It is aimed at developers who create tokens with the eosio.token contract and want to understand how much memory a contract consumes. It works best as a learning and testing aid rather than a full development suite.
Its documentation mentions Windows, but Windows support has not been verified. You will need Node.js and a terminal such as Command Prompt or PowerShell to run npm install. If you run into trouble, check the repository for details before you assume the problem is in your setup.
Yes, Savemyeosram is free and published as open-source code. You do not pay to download or use the program. The cost on EOS is a separate matter, since deploying a token contract consumes RAM, and RAM must be acquired with EOS.
You need Node.js with npm, plus a terminal such as Command Prompt or PowerShell on Windows. The author developed with Node.js 9.11.1 and says 8.x and 10.x should work in theory. After downloading the code, run npm install in the project folder to fetch its libraries.
No. The last code update was on July 8, 2018, and the latest listed version is v1.0. Because nothing has changed since then, expect dependencies to be outdated and check carefully how the tool behaves with current EOS software before relying on it.
RAM on EOS is the memory an account must hold to store data, including smart contract code and tables. Users acquire RAM with EOS, and its market price can change over time. Because token contracts occupy RAM, deploying a token can carry a real cost, which is the problem Savemyeosram addresses.
Verdict
Savemyeosram is a free, narrow tool for developers who want to understand the RAM cost of EOS token contracts. Its value today is mostly educational, because the project has seen no code updates since 2018 and Windows support remains unverified. If you are learning how RAM affects token deployment, read the code, test in a safe environment, and compare your results with current tools. It suits curious developers and students, not teams that need a maintained production toolchain.
