01 / EXPLORE
Let AI explore. Not improvise.
AI builds a constrained RulePlan from list and detail samples. The server validates and compiles it into extraction rules, never arbitrary model-generated code.
Page samples → RulePlan → GatherSpec
OPEN SOURCE · SELF-HOSTED · TRUSTED WEB DATA
Extrio.
Web data. With proof.
AI understands the page. You approve the rule. Every run is deterministic. Every item has a story.

01 / THE PHILOSOPHY
Intelligence at the start.
Certainty in every run.
Websites change. Models are probabilistic. Your data pipeline should not be a black box. Extrio separates discovery from execution, with an explicit boundary at every step.
02 / REVIEW
Evidence before execution.
Review fields, selectors, and sample validation together. A human approves publication. The immutable rule version is bound to its review with an Ed25519 signature.
Candidate → Human review → Frozen version
03 / RUN
A trace behind every item.
Runs pin a rule and data contract, recording quality decisions, checkpoints, and lineage. Site changes produce new candidates for review, never silent rule mutations.
Frozen rule → Deterministic run → Evidence
“
Not another crawler. A reviewable, repeatable, traceable way to work with web data.
THE EXTRIO WAY02 / THE WORKSPACE
From collection intent to item-level evidence.
A desktop workspace built for data operations. Rules, runs, and results stay connected, so the important questions do not disappear into logs.
Collected results and unconfirmed source coverage are reported separately and honestly.

03 / UNDER THE HOOD
No black-box magic.
Just a well-defined pipeline.
The control plane accepts intent. Independent workers do the work. AI helps generate rules; production runs follow the reviewed contract.

Exploration and rule compilation use a model. Human approval is a mandatory publication boundary.
Current single-instance topology. Distributed high availability and multi-tenancy are not current release claims.
Explore the architectureBUILT FOR THE AGENT ECOSYSTEM
Agents can use the data. Not bypass the review.
MCP exposes Extrio as a governed data tool. Agents can queue collection requests for review, trigger published rules, and query results with lineage. They cannot publish rules.

Trust begins with something you can inspect.
Read the code, the contracts, and the decisions. We would rather publish our boundaries and verification evidence than make promises you cannot reproduce.
Available
Self-hosted Public Alpha
AI rule generation and repair, human publication, deterministic collection, evidence export, Webhook, and MCP.
Validating
Real-world reliability
Cross-site compatibility, browser-rendered sources, and drift recovery. Current evidence is primarily repository tests and local reviews.
Target
Single-organization 1.0
Focused on sustained operation and experience acceptance for real teams. Hosted evaluation, public benchmarks, and multi-tenant hardening remain on the roadmap.
Build something dependable. Together.
