Tiger Data Introduces Ghost, a Purpose-Built Database Service for the Agentic Era
NEW YORK – Tiger Data, the team behind TimescaleDB and more than ten years of Postgres engineering, today announced the general availability of Ghost, an information service designed and built specifically for AI agents.
Ghost addresses a gap that has become one of the most pressing infrastructure problems in AI: developers need databases built for interacting with agents, not repackaged with tools designed only for humans.
“As teams implemented coding agents, research agents, and workflow agents at scale, they found that the underlying infrastructure was not designed for how the agents actually work,” said Ajay Kulkarni, founder and CEO of Tiger Data. “Ghost is specifically designed for that environment, providing an unlimited environment for agents to experiment without compromising the product.”
Ghost: A Web Site Service Designed for Developers and Their Agents
Agents are constantly trying and need to be classified to do it safely. If an agent fails, the blast radius should be a single database, not a shared database of other agents and dependencies. Ghost offers Postgres databases with fast forking, access via Ghost CLI or MCP server, and databases from ephemeral to always-on instances.
Ghost also enables a new type of testing to be economically viable. Investigating a large amount of distributed Postgres data, one task per task, each agent, per view, has historically been cost prohibitive – or outside the limits of the normal free tier limits – enough for teams to reuse a few shared spaces instead. Ghost’s per-query pricing model makes individual databases cheap enough to be managed as disposables, opening up trial-and-error workflows at a scale that wasn’t possible before.
Key features of Ghost:
Free tier with 100 hours/month and 1TB storage, hundreds of DBs and forks
Native integration with any MCP-enabled agent frameworks, including Claude Code, Cursor, Windsurf, Codex, Gemini CLI, and VS Code.
A robust dedicated tier when users are ready to graduate to production, starting at $10/month, built on Postgres’ high performance, TimescaleDB.
“I don’t use Ghost. My code agent Claude does,” said Jacky Liang, OpenRouter’s Developer Relations Leader. Only CLI/MCP experience is wise.”
Ghost was developed by the Tiger Data team, creators of TimescaleDB, the leading open source time series database built on Postgres. Ghost is built on the same foundation. Postgres offers a single query language, a single operating model, and a thriving ecosystem – the same infrastructure teams already know how to operate.
Ghost is available today, with a free tier of 100 computing hours per month and 1TB of storage space, and a limited amount of hard-earned money for paid titles. Documentation, implementation guides, and quickstarts are available at tigerdata.com.
