Features and specs

What each product offers, as listed by its team.

Metamorphic 11 features
E
Ember-cli 5 features
  • Post-quantum cryptography
    Hybrid ML-KEM-768 + X25519 key encapsulation, the same approach as Signal.
  • End-to-end encryption on all plans
    All data encrypted client-side before reaching the server. Every plan, not a paid upgrade.
  • Zero-knowledge email
    No plaintext email stored. Only an HMAC blind index for lookups.
  • Habit tracking
    Daily/weekly check-ins, streaks, and drag-and-drop reordering.
  • Goal setting
    Milestones, progress bars, and habit linking.
  • Self-reflections
    Mood tracking and daily prompts.
  • Schedule & calendar
    Recurring events, day planner, and printable views.
  • Progress insights
    Activity heatmaps and completion stats.
  • Family & group accountability
    Shared habits, shared goals, group dashboard, and member spotlights.
  • Client-side data export
    JSON/CSV export decrypted entirely in your browser. Server never sees plaintext.
  • Three encryption layers at rest
    Client-side E2E → AES-256-GCM in Postgres → LUKS disk encryption.
  • Convention over Configuration
    Ember-cli enforces strong conventions for file structure, naming, and project organization, which reduces decision fatigue and makes it easier for developers to jump between different Ember projects with minimal onboarding time.
  • Built-in Tooling
    Comes with a robust set of built-in tools including a development server, testing framework integration (QUnit), asset compilation, and live reload, reducing the need to manually configure and integrate third-party build tools.
  • Addon Ecosystem
    Ember-cli supports a rich ecosystem of addons that can be easily installed and integrated into projects, allowing developers to extend functionality without reinventing the wheel for common features.
  • Blueprints and Generators
    Provides powerful generator commands (blueprints) that scaffold components, routes, models, and other application pieces quickly, speeding up development and ensuring consistency across the codebase.
  • Stable Long-term Support
    Ember-cli follows Ember's release cycle with clear LTS (Long Term Support) versions, providing stability and predictability for teams maintaining large applications over time.

Possible disadvantages

  • Steep Learning Curve
    The strict conventions and unique architecture of Ember-cli can be difficult for newcomers to learn, especially those coming from more flexible frameworks or with no prior Ember experience.
  • Smaller Community Compared to Alternatives
    Compared to tools like Vite, Webpack, or CRA used with React/Vue, Ember-cli has a smaller community and ecosystem, which can mean fewer third-party resources, tutorials, and community-driven troubleshooting.
  • Build Performance
    For large applications, Ember-cli's build process can become slow, and while improvements have been made with embroider, some developers still report slower build times compared to more modern bundlers.
  • Rigid Structure
    The opinionated nature of Ember-cli, while helpful for consistency, can feel restrictive for developers who prefer more flexibility in structuring their applications or adopting non-standard patterns.
  • Migration Complexity
    Upgrading between major Ember-cli versions or migrating to newer build systems like Embroider can be complex and time-consuming, particularly for older or heavily customized applications.

Questions & Answers

As answered by people managing Metamorphic and Ember-cli.

Who are some of the biggest customers of your product?

Metamorphic's answer

Metamorphic is a new product and we don't disclose customer names. By design, we know as little about our users as possible — that's the point of zero-knowledge architecture.

What makes your product unique?

Metamorphic's answer

Metamorphic is a zero-knowledge, end-to-end encrypted habit tracker — every piece of user data is encrypted client-side before it ever reaches the server. Unlike competitors that treat encryption as a premium add-on, Metamorphic includes it on every plan, including Free. It also uses hybrid post-quantum cryptography (ML-KEM-768 + X25519), the same approach adopted by Signal and Apple iMessage, making it one of the first habit trackers with quantum-resistant key distribution. The server never stores plaintext — not even your email address.

Why should a person choose your product over its competitors?

Metamorphic's answer

Most habit trackers store your data in plaintext on their servers. Metamorphic never sees your data — all encryption and decryption happens in your browser. If the server were fully compromised, an attacker would get only opaque ciphertext. Beyond privacy, Metamorphic is a complete self-improvement platform: habit tracking with streaks and drag-and-drop reordering, goal setting with milestones and progress bars, daily self-reflections with mood tracking, a full schedule and calendar with recurring events and printable views, progress insights with activity heatmaps, and family/group accountability with shared habits and goals. You get the depth of a full-featured tracker with the privacy of an E2E encrypted system — no trade-off required.

How would you describe the primary audience of your product?

Metamorphic's answer

Privacy-conscious individuals and families who want a serious habit and self-improvement tool without surrendering their personal data to a third party. People who care about building better routines — daily habits, long-term goals, journaling, scheduling — but also care about who can read their data. Particularly relevant for anyone who has thought twice about logging personal struggles, health habits, or family goals into an app that stores everything in plaintext.

What's the story behind your product?

Metamorphic's answer

Metamorphic grew out of a personal conviction. Its creator, Mark Thayer, was building another app (Mosslet) around the time he was becoming a new dad. Reading Shoshana Zuboff's The Age of Surveillance Capitalism made him want a better digital world for his child. When Meta rolled back end-to-end encryption on its direct messaging, he was pushed to implement real E2EE in Mosslet — built on an asymmetric, password-derived key architecture.

The idea for Metamorphic itself came from his partner, who is passionate about psychology and behavior — always thinking about how to break old habits and form better ones. It clicked: something as personal as your habits, goals, and daily reflections should be private to only you, and you shouldn't have to worry about it being otherwise. So Metamorphic was built from day one around zero-knowledge architecture, where encryption is the foundation rather than an afterthought.

Which are the primary technologies used for building your product?

Metamorphic's answer

  • Elixir and Phoenix LiveView (real-time web application)
  • PostgreSQL with Ecto (database)
  • libsodium / NaCl (client-side end-to-end encryption)
  • @noble/post-quantum (ML-KEM-768 hybrid post-quantum key encapsulation)
  • Cloak / AES-256-GCM (application-level at-rest encryption)
  • Argon2id (password hashing and key derivation)
  • Tailwind CSS (UI styling)
  • Stripe (billing and subscriptions)
  • Oban (background job processing)
  • Fly.io (hosting, LUKS-encrypted storage volumes)
