Features and specs

What each product offers, as listed by its team.

Foam 6 features
LapseZero 8 features
  • Open Source
    Foam is an open-source tool, which means it is free to use and allows for community-driven development and contributions. Users can modify the source code to fit their specific needs.
  • Markdown Support
    Foam uses Markdown, a lightweight and easy-to-read syntax, making it simple to create and manage notes. This also allows for easy integration with other Markdown-based tools and platforms.
  • Integration with Visual Studio Code
    Foam is designed to work seamlessly with Visual Studio Code (VS Code). This provides users with a powerful and familiar text editor environment, complete with extensions and customization options.
  • Graph View
    Foam includes a graph visualization feature that helps users see and navigate the relationships between their notes, making it easier to understand and manage complex information.
  • Bidirectional Links
    Foam supports bidirectional links, allowing users to create connections between notes in both directions. This enhances the note-taking experience by enabling a more interconnected and dynamic information structure.
  • Community and Documentation
    Foam has a growing community of users and contributors, as well as comprehensive documentation. This support network helps users troubleshoot issues, share tips, and improve their knowledge of the tool.

Possible disadvantages

  • Limited to VS Code
    Foam relies on Visual Studio Code as its primary environment. Users who prefer different text editors or platforms might find this limitation restrictive and less convenient.
  • Learning Curve
    Although Foam leverages Markdown, users may still face a learning curve, especially if they are not familiar with VS Code or the specific features and extensions required to maximize Foam's capabilities.
  • Performance with Large Datasets
    Foam can struggle with performance issues when handling large datasets or a high number of notes. This can lead to slow response times and inefficient workflows.
  • Limited Mobile Support
    Foam is primarily designed for desktop use within VS Code, which means that mobile support is limited. Users looking for a seamless cross-platform experience might find this aspect lacking.
  • Customization Complexity
    While Foam offers a high degree of customization, setting up and configuring the tool to meet personal preferences and workflows can be complex and time-consuming for some users.
  • Automatic renewal
    Renews Let's Encrypt certificates when a third of their lifetime remains, so it keeps up as lifetimes shrink
  • Auto-deploy to servers
    Installs renewed certificates on Nginx servers over SSH or via the agent, and rolls back if a reload fails
  • Cloud and CDN deployment
    Deploys to AWS CloudFront and load balancers, plus Alibaba Cloud, Tencent Cloud and other cloud CDNs
  • Open-source deployment agent
    Outbound-only agent: no open ports and no stored SSH credentials; supports Nginx, 1Panel and Nginx Proxy Manager
  • Certbot and acme.sh takeover
    The agent discovers existing Nginx sites and lets you choose which ones LapseZero manages
  • DNS delegation
    A one-time CNAME per domain; no DNS API keys to hand over, wildcard certificates included
  • Certificate monitoring
    Watches the certificates on your public HTTPS sites and alerts you before they expire
  • Notifications
    Email, Webhook, Slack, Telegram, DingTalk, Feishu and WeCom alerts

Questions & Answers

As answered by people managing Foam and LapseZero.

What makes your product unique?

LapseZero's answer:

LapseZero doesn't stop at renewal. It issues and renews Let's Encrypt certificates, then installs them where they are actually served:

  • Nginx servers, over SSH or through a small open-source agent that only makes outbound connections
  • AWS CloudFront and load balancers, plus Alibaba Cloud, Tencent Cloud and other cloud CDNs
  • Existing Certbot and acme.sh sites, which the agent discovers so you can choose which ones LapseZero takes over

Your DNS credentials stay with you: a one-time CNAME when you add a domain is all LapseZero needs for every later renewal.

Why should a person choose your product over its competitors?

LapseZero's answer:

Certbot and acme.sh renew certificates well, but each server renews on its own and every CDN or load balancer needs its own deploy hook script. LapseZero renews once and pushes the certificate to every target from one dashboard, checks that the new certificate is live, and notifies you when something needs attention.

With Let's Encrypt's default lifetime dropping to 64 days in 2027 and 45 days in 2028, renewals and deployments happen far more often, so fewer scripts to maintain matters more. You can start free with 3 domains, 5 deployment targets and 5 certificate monitors, no credit card required.

How would you describe the primary audience of your product?

LapseZero's answer:

Developers, sysadmins and small DevOps teams who run their own Nginx servers or serve sites through AWS CloudFront, load balancers or cloud CDNs, and who would rather not maintain renewal and deploy scripts across all of them.

Which are the primary technologies used for building your product?

LapseZero's answer:

  • TypeScript, Next.js and React for the web app
  • Fastify, PostgreSQL (Prisma), Redis and BullMQ for the API and job queues
  • Go for the open-source deployment agent
  • ACME protocol with Let's Encrypt for certificate issuance

What's the story behind your product?

LapseZero's answer:

LapseZero started with my own day-to-day work. I manage a lot of domains at my company, along with their production and test servers, and more and more of them need certificates. As certificate lifetimes kept getting shorter, renewing and reinstalling them turned into constant maintenance, and it was easy to forget one.

So the first thing I built was SSL certificate expiry monitoring, to make sure nothing slipped through. Monitoring only tells you something needs doing, though, so the next step was to renew certificates automatically and deploy them to every server that uses them. That became the core of LapseZero.
