About AgentLock and StackMail

In their own words, as submitted to SaaSHub.

AgentLock
StackMail

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
StackMail 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.
  • Privacy-Focused
    StackMail emphasizes data privacy and security, offering encrypted email services without scanning user data for advertising purposes, appealing to privacy-conscious businesses.
  • Business-Oriented Features
    Designed specifically for businesses, it includes features like custom domain email, collaborative tools, calendars, and contact management tailored for professional use.
  • Competitive Pricing
    StackMail offers competitively priced plans compared to some larger email providers, making it accessible for small to medium-sized businesses.
  • No Ads
    Unlike some free email services, StackMail does not display ads to users, providing a cleaner and more professional email experience.
  • Custom Domain Support
    Users can easily set up email addresses with their own custom domain names, enhancing brand professionalism and consistency.

Possible disadvantages

  • Limited Brand Recognition
    As a newer or lesser-known provider compared to Google Workspace or Microsoft 365, StackMail may lack the trust and reputation that larger providers have established.
  • Fewer Third-Party Integrations
    Compared to major email service providers, StackMail may offer fewer integrations with third-party apps and services, limiting its versatility for some businesses.
  • Limited Advanced Features
    It may not offer the same breadth of advanced productivity and collaboration tools that come bundled with larger platforms like Microsoft 365 or Google Workspace.
  • Smaller User Community
    Due to a smaller user base, there may be fewer community resources, third-party tutorials, or troubleshooting forums available online.
  • Uncertain Long-Term Support
    As a smaller company, there might be concerns regarding the long-term viability, updates, and continued support of the service compared to more established providers.

Questions & Answers

As answered by people managing AgentLock and StackMail.

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.
