Layerbase is a managed database platform built around flat monthly pricing instead of metered billing. One account gives you 18 database engines in the cloud, including PostgreSQL, MySQL, MariaDB, FerretDB (MongoDB wire protocol), Valkey, DuckDB, ClickHouse, QuestDB, and InfluxDB, all managed from a single dashboard with query consoles for every engine, automatic backups, database branching, and wake-on-connect hibernation.

Plans are Free, Solo ($5/month), and Pro ($15/month). Dedicated servers ($35-$120/month) have no database or branch limits. All billing is unmetered, so your monthly bill is always predictable. Free-tier databases hibernate when idle and wake on connection instead of being deleted, so side projects keep working. Pro adds features like mTLS client certificates for PostgreSQL.

The same team ships Layerbase Desktop, a macOS app for running and browsing local databases, and the Layerbase CLI on npm, which manages 21 engines locally for development, CI pipelines, and AI agents.

Datomic features and specs

  • Immutability
    Datomic employs an append-only data model where data is never overwritten but instead appended, ensuring historical data is always available and providing strong consistency.
  • Time Travel Queries
    Datomic allows you to query the database as of any point in time, facilitating auditing and debugging by allowing easy access to historical data states.
  • Rich Data Model
    Supports complex data types like maps and sets directly within its schema, providing a flexible way to represent data.
  • ACID Transactions
    Datomic supports fully ACID-compliant transactions, ensuring reliable and predictable database operations.
  • Scalability
    Separates storage and compute, allowing for horizontal scaling of read operations, making it suitable for handling large datasets.
  • Query Flexibility
    Offers a powerful query language that supports recursive queries, making it suitable for complex data retrieval needs.

Possible disadvantages of Datomic

  • Complexity
    The architecture of Datomic can be complex to understand and implement, particularly for teams unfamiliar with its design principles.
  • Cost
    Can be expensive to operate, especially in a cloud environment, where costs increase with the amount of data stored and the compute resources required.
  • Limited Write Throughput
    Due to its append-only design, Datomic can have limited write throughput, which may not be suitable for applications with heavy write requirements.
  • Closed Source
    Datomic is a proprietary database system, which may not appeal to organizations that prefer open-source solutions.
  • Learning Curve
    Requires a learning curve as its conceptual model and query language are different from traditional databases, potentially requiring additional training.
  • Dependency on AWS
    Relying on AWS ecosystem for the storage backend can limit choices for deployment environments, impacting flexibility.

Layerbase features and specs

  • Database Engines
    18 cloud engines: PostgreSQL, MySQL, MariaDB, FerretDB, Valkey, ClickHouse, DuckDB, QuestDB, InfluxDB, and more
  • Database Branching
    Fork a database near-instantly, with lineage tracking and one-click reset from parent
  • Flat Pricing
    Free tier plus Solo $5/mo and Pro $15/mo; dedicated servers $35-$120/mo; billing is never metered

Questions & Answers

As answered by people managing Datomic and Layerbase.

What makes your product unique?

Layerbase's answer:

Layerbase gives you 18 database engines in one account with flat monthly pricing. Instead of running Postgres on one vendor, Redis on another, and ClickHouse on a third, you provision all of them from a single dashboard, and the bill never changes based on usage. Every engine gets the same tooling: query console, automatic backups, branching, and wake-on-connect hibernation, so a free-tier side project stays alive instead of being deleted for inactivity.

Why should a person choose your product over its competitors?

Layerbase's answer:

Pick Layerbase when you want a predictable bill and more than one kind of database. Most competitors host a single engine and meter usage, so costs are hard to forecast and a second engine means a second vendor. Layerbase replaces that stack with one account: Postgres for your app, Valkey for caching, ClickHouse for analytics, FerretDB for documents, all on Free, Solo ($5/month), or Pro ($15/month) plans, with dedicated servers from $35/month when you outgrow shared capacity. The free tier hibernates idle databases and wakes them on connection rather than deleting them.

How would you describe the primary audience of your product?

Layerbase's answer:

Developers and small teams who run real products without a dedicated ops person: indie hackers with side projects, startups that want Postgres plus a cache plus analytics without three vendors, and agencies managing databases for multiple clients. The CLI also makes it a fit for CI pipelines and AI coding agents that need to spin up disposable local databases.

What's the story behind your product?

Layerbase's answer:

Layerbase started as a command-line tool for spinning up local databases without wrestling with Docker configs or Homebrew versions: one command, any engine, running in seconds. Once that worked for local development, the obvious next question was why the cloud version of the same idea had to mean a different vendor for every engine and a bill that changes every month. So we built the managed platform around the same principles: every engine in one place, provisioning in seconds, and flat pricing you can predict. The desktop app and the CLI are still there for local work, and the cloud picks up where they leave off.

Which are the primary technologies used for building your product?

Layerbase's answer:

TypeScript end to end. The web app and dashboard are Next.js and React, the desktop app is Electron, and the CLI ships on npm. Databases run in containers on bare-metal servers with ZFS storage, which is what makes near-instant database branching possible, and connections are routed with TLS/SNI so hibernated databases can wake on connect.
