Any records, files or feeds. No pipelines to build.

Make your data searchable.

Import it once and it's searchable straight away — by the people using your site and by AI agents over MCP. Fast results, smart filters, as-you-type suggestions, and nothing for you to run.

Connect your data

Upload JSON or CSV, sync a file we keep fresh, or connect a live feed we keep in sync.

Mark your fields

Choose what's searchable, filterable and facetable, with no schema migrations.

It's searchable

Straight away, and for everyone: your website, your app, and your AI agents alike.

Everything search. Nothing to run.

Import your data, choose what's searchable, and Search Stack handles everything behind the scenes, right down to the search box on your page.

Search quality, as a number

Pin a version, let a judge score the searches your users really make, and get a single pass rate you can watch. Change a model or reranker, re-run, and see in seconds whether search got better or worse, catching a regression before a customer does. It’s the one thing hosted search doesn’t give you.

Run your whole search backend from an agent

Every operation is a tool an AI agent can call over our built-in MCP server: not just searching, but creating lists, importing records, and configuring models, rerankers and judges. Point Claude at your data with one command and it does the rest, scoped to the API key you give it. And it works the other way too — your own agents get a ready-made way to search your data, the same key-scoped access that powers the Playground in our console.

Your search API, ready instantly

Every list you import gets its own web address that answers search requests: versioned, always on, and nothing for you to maintain.

Search, filter, facet and locate

Combine full-text search with filters, counts by category and “near me” queries, all answered together, in one go.

Point it at your data, it stays searchable

Sync a file or connect a live feed, and your search updates itself as your data changes — no re-import, and no pipeline to babysit.

Build it with Claude

Install our Claude skill and just ask. Claude builds a search page on your records, imports your data, and answers questions about them.

“Build me a search page for my products list.”

Why Search Stack, and not the others.

Most tools sell you a search API to wire up. We make your data searchable — over our managed pool or the backend you already pay for.

Your backend, or ours

Run on our managed pool, or point Search Stack at the Elasticsearch, Azure AI Search, OpenSearch or PostgreSQL you already run. Same API either way — and on your own backend it's free permanently.

Agent-native and multimodal

Text, vector, hybrid, geo and grouping, plus image and video search — and an MCP server your agents call directly, to search and to configure. Most hosted search does text and stops.

A bill you can predict

Flat monthly tiers, with no per-search or per-record metering — the traffic spike that makes your search worth having doesn't arrive as an invoice.

Unlimited records & storage

Higher tiers raise the limits — records, storage, your own index. They never unlock a feature: evals, judges, rerankers, embedding models and the MCP server come with the same generous ceilings whether you pay $29 or $299. Already running your own search cluster? Add Search Stack on top and there's nothing to pay at all.

See what's in each plan

It's a plan, not a trial.

Every account begins on the free plan, and it's a plan, not a trial — nothing counting down. Import a JSON or CSV file and your search is live, with suggestions, facets, agents and versioning already wired in. Every feature is switched on, right down to the quality evals. Upgrade the day your data outgrows it, and not before.
