About AgentLock and Modular JavaScript

In their own words, as submitted to SaaSHub.

AgentLock
Modular JavaScript

AgentLock is a security gateway between AI agents and the services they touch. An agent sends its intended action - an HTTP call, an MCP tool call, a browser session, an SSH command - through AgentLock, where a policy decides whether it runs, is blocked, or needs human approval. Approvals arrive...

Features and specs

What each product offers, as listed by its team.

AgentLock 3 features
Modular JavaScript 5 features
  • Human Approval Gateway
    Every agent action runs through a policy: allowed, blocked, or held for a human approval that arrives on the phone and expires if nobody answers.
  • Zero-Knowledge Credential Vault
    Secrets are stored AES-256 encrypted and injected only at execution time, so the agent never sees the key itself.
  • Audit Trail And Undo
    Each request, decision and result lands in a timeline, and supported actions can be undone afterwards.
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.

Overall verdict

  • Modular JavaScript (mjavascript.com) is a solid resource for developers looking to learn best practices around modular design patterns in JavaScript, though its value depends on your current skill level and how current the content remains given the fast pace of JS ecosystem changes.

Why this product is good

  • Focuses specifically on modularity, a critical but often overlooked aspect of scalable JavaScript development
  • Covers practical patterns for organizing code, managing dependencies, and structuring larger applications
  • Can help bridge the gap between basic JavaScript knowledge and professional-grade architecture skills
  • Often includes real-world examples rather than purely theoretical concepts
  • Useful for understanding module systems like CommonJS, ES Modules, and build tool configurations

Recommended for

  • Intermediate JavaScript developers wanting to level up their code organization skills
  • Developers transitioning from simple scripts to larger, maintainable applications
  • Teams looking to establish consistent modular coding standards
  • Self-taught programmers seeking structured guidance on architecture
  • Backend or frontend developers working with Node.js or modern JS frameworks who need better module management practices

Questions & Answers

As answered by people managing AgentLock and Modular JavaScript.

What makes your product unique?

AgentLock's answer

AgentLock sits between the agent and the outside world instead of trusting the agent to behave. Every HTTP call, MCP tool call, browser action or SSH command becomes a request that a policy decides on, and anything sensitive waits for a human approval that arrives on the phone. Credentials live in the vault and are injected only at execution time, so an agent can use a key without ever seeing it - and if nobody approves in time, the action simply does not happen.

Why should a person choose your product over its competitors?

AgentLock's answer

A secrets manager stores keys, but once an agent holds one, nothing stops it from making the wrong call. AgentLock covers both halves: the encrypted vault plus a gateway with policies, human approval, automatic redaction, a full timeline and undo for supported actions. It is available as an MCP server and an SDK, so an existing agent can be routed through it without a rewrite, and the free plan already covers 100 actions a month with one agent.

How would you describe the primary audience of your product?

AgentLock's answer

Developers who run autonomous agents against real systems - deployments, payments, mail, customer data - and want an audit trail and a stop button instead of hoping the prompt holds. Small teams also use it to let an agent work with shared credentials without handing the keys to every team member or to the model itself.

Which are the primary technologies used for building your product?

AgentLock's answer

TypeScript across the stack: a React dashboard on Vercel, Supabase with Postgres, Auth and Edge Functions for data, policies and the encrypted vault, a self-hosted runner for actions that need a private network, React Native for the iOS and Android approval app, and Stripe for billing.
