The AI Developer Platform
Built on an Intelligent Database

Database, auth, realtime, queues, file storage, edge functions, and auto-generated REST APIs in one platform. MongoDB and Meteor.js compatible. Just change your connection string.

context-search.ts
const context = await db
  .collection('agent_memory')
  .aggregate([{
    $contextSearch: {
      query: userMessage,
      vector: {
        path: "$embedding",
        limit: 20
      },
      temporalDecay: {
        field: "timestamp",

      },
      expand: {

The Problem

Your Database Wasn't Built for AI

Building AI applications means stitching together databases, vector stores, auth providers, realtime engines, queues, and file storage. Six vendors. Six bills. Six failure domains. There's a better way.

Six Services Just to Ship an AI App

Database, vector store, auth provider, realtime engine, message queue, file storage. Six vendors, six SDKs, six bills, six failure domains. Your "application" is mostly glue code holding them together.

Context is Scattered Across Services

Your agent's memory lives in one service. Its retrieval context in another. Auth in a third. Realtime sync in a fourth. Every query requires glue code to merge them. Every inconsistency becomes a hallucination.

No Memory Lifecycle Management

Agent conversations pile up with no way to decay, archive, or summarize. You build custom TTL logic, manual archival pipelines, and brittle cleanup scripts. Or your context windows overflow.

The Multi-Vendor Tax

Auth0 for auth. Pusher for realtime. SQS for queues. S3 for files. Each charges separately. Each scales differently. Each has its own security model. You spend more time integrating services than building your product.

Architecture That Just Works

Not a proxy. Not a compatibility layer. A complete database engine with native storage tiering.

Everything You Need to Build AI Applications

An intelligent database with a complete developer platform built in. Context search, auth, realtime, queues, branching, and auto-generated APIs - all in one system.

AI Context Engine

Native $contextSearch combines vector similarity, temporal decay, relationship traversal, and session scoping in a single query. No glue code. No context assembly layer.

Built-in Auth & Document-Level Security

JWT tokens, API keys, OAuth providers, and MFA built into the platform. Document-level security policies enforce row-level access right in the storage engine.

Intelligent Tiering

Data automatically flows from NVMe hot storage to Parquet cold storage based on access patterns. Queries span both tiers transparently. 60-80% cost reduction.

Auto-Generated REST API

Every collection gets instant REST endpoints with filtering, sorting, and pagination. Auto-generated OpenAPI specs. No backend code required.

Database Branching

O(1) copy-on-write branches for dev, test, and preview environments. Branches share storage via MVCC snapshots. Merge back with conflict detection.

Edge Functions & Triggers

Run code on database events. Auto-generate embeddings on insert, fire webhooks on update, schedule cron jobs. All from your database.

Time Travel Queries

MVCC snapshots let you query data at any historical timestamp. Debug agent hallucinations, satisfy auditors, and build undo functionality.

Broadcast & Presence

WebSocket-based realtime subscriptions, broadcast messaging, and presence tracking. Live database changes pushed to connected clients.

Built-in Queues

Durable message queues with visibility timeouts, dead-letter queues, and ACID guarantees. No SQS or RabbitMQ needed.

MCP Server for AI Assistants

AI coding assistants query your schema, run queries, and write database code directly from the IDE via Model Context Protocol.

Complete Platform

Replace Your Entire Backend Stack

Stop stitching together six vendors to build one product. Thermocline gives you the database, auth, realtime, queues, file storage, and APIs in one platform with one security model.

Why Thermocline

What No Other Database Does

Thermocline isn't a vector database with features bolted on. It's a complete AI developer platform that replaces your entire backend stack: database, auth, realtime, queues, file storage, and APIs.

Native Context Search

Vector search is table stakes. Context search is the game.

$contextSearch combines vector similarity with temporal decay scoring, relationship expansion, and session scoping. One query returns ranked, relevant context, not just similar vectors.

Temporal Decay Scoring

Recent memories matter more

Built-in exponential, linear, and gaussian decay functions score results by recency. A conversation from yesterday outranks a similar one from last month. No application-side re-ranking.

Agent Memory Lifecycle

From session to archive, automatically

Session collections with configurable TTL, auto-archival to cold storage, and summarization hooks. Your agent's long-term memory manages itself without custom pipelines.

Intelligent Storage Tiering

Hot performance. Cold economics.

Data automatically flows between NVMe hot storage and S3 Parquet cold storage based on access patterns. Queries span both tiers transparently. No other document database does this.

Time Travel Queries

Query any point in history

MVCC snapshots let you read the database as it existed at any timestamp. Debug agent hallucinations, satisfy auditors, and build undo functionality with a single query parameter.

MongoDB & Meteor.js Compatible

Change your connection string. That's it.

Full wire protocol compatibility. Mongoose, Prisma, PyMongo, and Meteor.js all work out of the box. Existing application code, queries, and indexes carry over with zero changes.

Context-Aware Retrieval in a Single Query

Context-Aware Retrieval in a Single Query

Traditional RAG fetches similar vectors and hopes for relevance. Thermocline's $contextSearch combines vector similarity with temporal decay so recent conversations score higher than old ones. Add relationship expansion to pull in referenced documents. Add session scoping to stay within the current interaction. One query returns precisely ranked context.

Agent Memory That Manages Itself

Agent Memory That Manages Itself

Every AI agent accumulates context that needs to age, archive, and summarize over time. Thermocline handles this natively. Active sessions live on hot NVMe. As conversations age, they automatically tier to cold storage. Summarization hooks condense long histories without losing retrieval access. No cron jobs. No custom TTL logic.

Hot Performance. Cold Economics.

Hot Performance. Cold Economics.

Your active data lives on NVMe SSDs with sub-millisecond reads. Historical data automatically moves to columnar Parquet on object storage at 1/10th the cost. Every query transparently spans both tiers. You get the performance of a hot database and the economics of a data lake, without managing either.

Cost Savings

Replace Four Services. Cut Costs by 80%.

Stop paying for a vector database, an operational database, a context layer, and cold storage separately. Thermocline replaces them all.
