The web, wired
into your local agent.

wigolo is a local-first MCP server that hands any coding agent the whole web — search, fetch, crawl, extract, cache, and research. Built to stand with the best tools in the lane. No API keys. No cloud. No metered bill.

The tools

Your agent is smart. Its web access isn't.

// every result explains itself
{
  "excerpt": "Logical replication replicates data…",
  "score": 0.87,
  "breakdown": {
    "semantic": 0.91,
    "lexical": 0.74,
    "engine_consensus": "4/5 engines"
  },
  "source_span": { "start": 1284, "end": 1571 },
  "citation_id": "f38b44c100e4"
}

Evidence, not blue links

See the receipts

One MCP call fans a query array across many engines in parallel. Every result comes back with a transparent score breakdown, byte-offset source spans, and citation IDs — output your agent can quote.

Routing on observable signals

How it works

The fetch ladder escalates to a real browser on what it sees — SPA markers, challenge bodies, thin content — not domain guesses. It learns per-domain, and unlearns when a site stops needing it.

agent → cache "postgres logical replication"
wigolo → 3 hits · hybrid keyword + semantic

Everything it sees, it keeps

Get started

Every response lands in a local store under ~/.wigolo/ — full text, keyword index, and on-device vectors. Asking again is instant and costs nothing; find_similar and change detection build on it.

Research that writes itself

All 10 tools

research decomposes a question, fans out sub-queries, fetches sources, and hands back a cited brief. agent runs an autonomous plan → search → fetch → extract → synthesize loop with a step log and time budget.

Open Source

Free, and meant to
stay that way

wigolo is AGPL-3.0 — free to use, modify, and self-host, including inside a company. The license keeps it open: nobody can close it up and sell it back to you. Maintained, not paywalled.

built and maintained by @KnockOutEZ — one developer, going up against three funded teams.

Parity

Same fight.
Different physics.

The paid tools in this lane are genuinely good — that's what makes the parity interesting. What still separates wigolo isn't quality. It's where the work happens.

Feature standing as of July 2026 — check each vendor's docs for current state. One cold query, four tools, judged on the evidence alone — watch the full run.

The meter: a metered cloud API's cost climbs with every query while wigolo stays flat at zero dollars — illustrative pricing
Ask twice, pay never: first query hits the live web in 3.6 seconds, the second answers from local cache in milliseconds, the third still answers offline

Give your agent the whole web.

One command installs the local engine and wires it into your agent — search, fetch, crawl, extract, cache, and research, with no API key.

Install in two minutes

Working in under two minutes.

1

Install & wire your agent

Any of these, comma-separated: claude-code · cursor · codex · gemini-cli · vscode · windsurf · zed · antigravity

That's the whole setup — search, fetch, crawl, extract & cache need no API key.

2

Check it's healthy

Verifies the local engine — search, browser, on-device models.

Node ≥ 20 · macOS / Linux / Windows · no account, no key.

3

Optional — answer synthesis

research, agent, and answer-format search use an LLM to write the final text. Any provider works — or stay fully local.

A free-tier key is plenty — or keyless with a local model server.
