Infeos is an open source development framework for building, testing and deploying EOSIO dApps. It is written mainly in JavaScript and aimed at developers who already work with the EOSIO protocol and npm. It is free and runs on Windows through a Windows build or installer, with Docker Desktop as the practical prerequisite. Before you start, note that the project has had no code updates since March 2019, so treat it as an unmaintained tool rather than a current production choice.
The framework bundles steps that usually take a lot of setup time: preparing an environment, starting a local blockchain node, writing unit tests and configuring deployment. Its main appeal is speed and a single project layout for anyone who wants to learn EOSIO development on a local node before touching a live network. The sections below cover what it does, how to install it on Windows, and where it fits compared with other development tools.
What Is Infeos and Who Is It For?
Infeos is a framework that wraps the common tasks of EOSIO development into one toolkit. EOSIO is a blockchain protocol on which developers build decentralized applications, or dApps, whose core logic lives in smart contracts. Building those contracts usually means assembling a local environment, running a test node, writing tests and preparing a deployment pipeline by hand. Infeos aims to package those steps.
The audience is mostly JavaScript and TypeScript developers who already use npm and want to stay in that ecosystem. It also suits developers new to EOSIO who want a guided way to see how a project fits together. Teams evaluating EOSIO before committing to a chain can use it to prototype quickly. It is less suited to people looking for a visual, no-code environment, since the workflow assumes comfort with the command line and project configuration.
How EOSIO dApps Differ From Ethereum Projects
Many developers first learn smart contracts on Ethereum, where Solidity and EVM tooling dominate. EOSIO uses its own protocol, account model and contract conventions, so skills and tools do not transfer one to one. A contract written for EOSIO is compiled and deployed differently from an Ethereum contract, and the testing approach reflects that.
This is why a framework like Infeos can be useful: it groups EOSIO-specific steps, such as preparing a local chain and deploying contracts to it, into one workflow. Without such tooling, developers must learn the underlying protocol and assemble the pieces themselves. The trade-off is that a framework tied to one ecosystem has a narrower audience and depends on that ecosystem staying active.
Real-World Use Cases for a Local EOSIO Test Network
Consider a small team building a token-based game on EOSIO. Before any real transaction happens, they want to check that contract rules hold when players do unexpected things. A local node lets them reset state, replay scenarios and run unit tests without spending resources on a public network.
A second scenario is a developer comparing how a planned product would behave on EOS, Telos and Worbli. Choosing a network profile at startup makes it simple to rerun the same test suite against each target. A third use is teaching: instructors can give students a repeatable environment, so everyone starts from the same configuration. In each case the value is repeatability, which is easier to achieve when the environment is automated.
Key features
Fast environment setup
One-command local node
JavaScript unit tests for smart contracts
Configurable environments and deployment
Standard dApp project structure
Supported coins
Infeos is built for the EOSIO protocol and can start a full local node for the EOS, Telos or Worbli networks. It does not target Ethereum-style chains, so contracts for other ecosystems need different tooling.
How to install Infeos on Windows
- 1
Install Docker Desktop
Download Docker Desktop for Windows from its official website and run the installer. Infeos on Windows relies on Docker Desktop, so make sure it is installed and running before you set up the framework. Restart Windows if the installer asks you to.
- 2
Get the Infeos package
Download the Windows build or installer from the project's official GitHub repository and its Releases page. The latest version listed is v0.1.32. Download only from these official GitHub sources and avoid repackaged copies from other sites.
-
Verify and install
If a SHA-256 checksum is published with the release, compute it with PowerShell using Get-FileHash and compare the result with the published value before running the installer. Then run the installer and follow the prompts to finish setup.
System requirements
- Windows with Docker Desktop for Windows installed
How to use Infeos
Once installed, the workflow follows the framework's main stages. The steps below outline a typical first session. Check the project repository for the exact commands.
- Set up the environment for your first project and confirm that Docker Desktop is running.
- Start a local node and choose EOS, Telos or Worbli as the network profile.
- Create or open a dApp project using the master-contract structure.
- Write your smart contract logic using the JavaScript-based tooling.
- Add unit tests in JavaScript and run them against the local node.
- Adjust environment and deployment settings, then deploy to the network you have chosen.
Pros & cons
- Free and open source
- Quick setup on Windows once Docker Desktop is installed
- Local node startable with a single command
- Unit tests written in JavaScript
- Configurable environment and deployment settings
- Standard project structure for dApps
- No code updates since March 2019
- Requires Docker Desktop on Windows
- Focused only on EOSIO, not Ethereum-style chains
- Tooling around EOSIO has moved on since 2019, so compatibility with current releases is not guaranteed
Is Infeos safe?
Infeos is a development framework rather than a wallet, but it touches deployment settings and account credentials, so treat it with care. Download the Windows build or installer only from the official GitHub repository or its Releases page, not from mirror sites. If a SHA-256 checksum or signature is published with the release, verify it before running the installer. Never enter a seed phrase or private key on third-party websites, and keep keys out of project files you share or commit to version control. The project has had no code updates since March 2019, so review the code and its dependencies yourself before using it on any network that matters.
- Official source only. Download from github.com/infiniteXLabs/infeos. 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
Infeos is narrower than most tools on this list. It targets EOSIO specifically, while Remix Desktop is an IDE for Solidity on Ethereum-style chains and Foundry (forge, cast, anvil) is a toolkit for EVM smart contracts. Anchor serves Solana programs, and Tenderly CLI focuses on debugging and monitoring contracts rather than building them from scratch. Infeos stands out for its JavaScript workflow and its one-command local node for EOSIO networks. If you work on EVM chains or need actively maintained tooling, the other tools are usually the better starting point. Solidity is the compiler for Ethereum contracts, so it complements a framework rather than replacing one.

Frequently asked questions
Yes, Infeos is free and open source. You can get it from the project's GitHub page without paying a license fee. Free software still requires your own review, since the project has not been updated since March 2019.
Yes, Infeos is available for Windows as a build or installer. Docker Desktop for Windows must be installed first. The project also lists macOS and Docker among its supported platforms.
It can be, if you download it only from the official GitHub repository and check any published SHA-256 checksum before running the installer. Because it handles deployment settings, never enter seed phrases or private keys on third-party websites. The lack of updates since 2019 is a separate risk to weigh.
Infeos can start a full local node with one command for EOS, Telos or Worbli. You choose the network when you set up the node. This lets you test against each network's configuration before deploying anything.
No. The project has had no code updates since March 4, 2019, and the latest listed version is v0.1.32. It is best treated as a reference or learning tool rather than an actively supported platform.
Infeos is built on JavaScript and TypeScript, with npm and eosjs. That makes it familiar for web developers, who can write smart contract tests in the same language they already use.
Remix Desktop is an IDE for Solidity, aimed at Ethereum-style contracts, while Infeos targets EOSIO. Infeos focuses on building, testing and deploying EOSIO dApps through a JavaScript framework rather than a visual editor.
Verdict
Infeos suits developers who want a free, JavaScript-based way to learn or prototype EOSIO dApps on Windows, especially on a local node using EOS, Telos or Worbli profiles. Because the project has not been updated since March 2019, it is better suited to study, experiments and reference than to new production work. Check the latest version on the official website before you install, and compare it with the alternatives below if you need actively maintained tooling.
