Enterprise DAG pipelines. Vectorized C++ speed. Zero cloud egress.
Stop uploading confidential datasets to third-party clouds. RTIO runs a vectorized columnar database and visual DAG studio inside your browser tab — private, deterministic, and 100% free for local compute. After the page has loaded once, that pipeline still runs with the network off.
Live Sandbox · In-Browser Execution
This is not a video or simulation. Run a live 50,000-row pipeline directly in your browser tab. Inspect the nodes, check DevTools (0 bytes egress), and witness vectorized C++ speed.

The Local-First Architecture
Eliminate the tradeoff between data privacy and developer speed. RTIO brings columnar query execution and automated profiling directly into your browser tab with zero cloud egress.
In Local Mode, raw customer records never leave your browser tab. The AI planner only sees anonymized statistical metadata (types, distributions, null counts). DevTools verifiable.
Never let AI hallucinate your transformations. RTIO compiles visual steps into deterministic DuckDB-WASM SQL recipes with SHA-256 cryptographic audit chaining.
Orchestrate complex diamond pipelines across 15 specialized node types, or double-click any node to clean directly in an interactive virtualized spreadsheet grid.
No upload. No seat.
Drop the file in the tab. Clean it, join it, export it on the computer that already had it. The studio is free because nothing had to be rented to look at those rows. A 2am run with the laptop shut is the part we charge for.
Solutions
RTIO is domain-agnostic but integrates seamlessly with the tools you already use. Choose your path.
Stop writing boilerplate. Start building deterministic, reproducible pipelines.
The secure, metadata-only MCP server you can actually trust.
Privacy-first processing with automated PII masking and zero raw data egress.
Data engineers shouldn't pay a recurring SaaS tax to clean confidential records on their own hardware. RTIO executes locally in your browser with zero egress. When you need 24/7 unattended cloud automation, pay only for the compute credits you actually consume.
For analysts, engineers & privacy-first teams working on their devices.
For teams needing 24/7 unattended pipelines running while laptops are closed.
Pay only for data volume processed & compute seconds
For healthcare, financial institutions & strict compliance organizations.

“We built RTIO so data teams never have to rent expensive cloud clusters or leak confidential rows just to clean and transform datasets that modern laptops can crunch in milliseconds.”
Transform and clean tabular datasets directly in browser RAM with sub-second latency. Raw user records never touch remote servers.
Client-side PII detection, Laplace differential privacy noise injection, and AES-256-GCM encrypted BYOK vault stored strictly in IndexedDB.
FAQ
RTIO is a local-first, AI-native analytical engine and data preparation studio. It combines a 15-node visual DAG pipeline builder with an interactive spreadsheet Data Wrangler, powered entirely in your browser by DuckDB-WASM. Build, clean, transform, and export datasets at C++ vectorized speed with physical zero raw data egress in Local Mode.
Upload data or connect a source. The AI Agent inspects schema-level metadata only (column names, types, null percentages, distributions) — never your actual records. It generates in-browser MCP tool calls that compile into deterministic DuckDB-WASM SQL recipes. The browser verifies each transformation locally before executing it with a cryptographic SHA-256 audit trail.
Yes. In Local Mode (the default), raw data never leaves your browser tab — it runs in DuckDB-WASM memory and persistent OPFS on your own device. The AI planner only receives statistical metadata via your own encrypted API keys (BYOK stored in IndexedDB via AES-256-GCM). If you opt into Cloud Compute mode for low-power devices, processing is strictly ephemeral and data is wiped immediately after execution.
Yes. Save any pipeline as a reusable template and apply it to new datasets with a single click. Templates can be exported as clean SQL, Parquet, or Python scripts for integration into your existing workflows.
RTIO supports structured files (CSV, TSV, JSON, JSONL, Excel .xlsx/.xls, and Apache Parquet), unstructured documents (in-browser tabular extraction from PDFs, invoices, Markdown tables, and text reports via Document Extractor), live REST APIs (HTTP GET/POST), and cloud object storage (AWS S3, Cloudflare R2, Google Cloud Storage, MinIO).
After the site has loaded once, the dashboard opens with the network off and a local pipeline still runs on this computer. The file you dropped stays in this browser. It is not copied into a synced folder unless you export it. API sources, API destinations, and storage connectors still need a connection, and those nodes are labeled Online. A portable copy is a folder that starts the same pages on a computer without signing in to rtio.io. That start is Windows for now.
Local Mode is 100% free with unlimited local compute — you leverage your own device's hardware with zero subscription tax. For unattended background automation and scheduled pipelines running on our cloud, we offer a compute credit tier. Enterprise plans with custom connectors and SSO are available on request.
