About JSONLint and AgentLock

In their own words, as submitted to SaaSHub.

JSONLint
AgentLock

No description of JSONLint yet.

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.

JSONLint 5 features
AgentLock 3 features
  • User-Friendly Interface
    JSONLint offers a simple and intuitive web interface that makes it easy to validate JSON data without the need for advanced technical skills.
  • Error Highlighting
    The tool highlights exactly where the errors are in the JSON data, making it easier to identify and correct mistakes quickly.
  • Free to Use
    JSONLint is freely accessible to anyone with an internet connection, making it a cost-effective solution for validating JSON data.
  • JSON Formatter
    In addition to validating JSON, JSONLint also offers functionality to format and beautify JSON data, improving readability.
  • Quick Processing
    The tool processes JSON data quickly, providing almost instant feedback which is useful during development and debugging.

Possible disadvantages

  • Internet Connection Required
    JSONLint is a web-based tool, so it requires an active internet connection to function, which can be a limitation in offline environments.
  • Basic Features
    While JSONLint is excellent for simple validation and formatting, it lacks more advanced features like schema validation or integration with development environments.
  • No API
    JSONLint does not offer an API for programmatic access, limiting its use in automated workflows and larger development pipelines.
  • Ads on the Website
    The website includes advertisements, which can be distracting for users and might affect the user experience.
  • Limited Customization
    The tool does not offer much in terms of customization options for how errors are displayed or how JSON is formatted, which might not meet all user needs.
  • 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.

Questions & Answers

As answered by people managing JSONLint and AgentLock.

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.
