One stack. Four flagships.
Three notable mentions.
The Legion Code Inc. product line is a connected toolchain for the developer in the time of AI. Each product can stand alone — and each is more useful when the rest of the stack sits next to it.
Legion Secure
// Find every credit card you're leaking. Then fix it.
Legion Secure is the front door. The free Quick Scan finds keys, vulnerable deps, and PCI surface in five minutes — the lead-magnet that gets you in the room. The paid Deep-Scan is what starts digging the moat: human-verified findings with code-level fixes, written next to your own snippet. Not "a vulnerability exists." The patched line, ready to paste.
// Starts digging the moat.
Three-layer scan
Secrets · Dependency CVEs · PAN regex. Every layer, every scan.
Signed PDF + JSON report
Cryptographically signed deliverable your processor, bank, or insurer expects.
Code-level fix, not finding
Deep-Scan ships the patched snippet, not "something's wrong here."
Sandboxed, never stored
Ephemeral VM, self-destructs at the end. Your source never persists.
Legion Atlas
// Map what you built. Document it to a standard.
Legion Atlas walks your repository, infers the architecture, and writes the docs you never wrote. To a strict standard — call graphs, data flows, side-effects, API contracts, dependency graph. The output is the documentation a senior engineer would have written before quitting last quarter. This is the second wall of the moat: a codebase you can hand to a new hire, an acquirer, or an insurer.
// Finishes the moat, raises the drawbridge.
Architectural inference
Call graphs, data flows, side-effects. Every module, every contract, every cross-talk.
Living documentation
Re-generated on every commit. Never out of date because it's never hand-written.
Strict standards spec
Code mapped to a documented style. Not "best practices." One spec we will defend.
Acquisition-ready output
The packet a buyer's diligence team gets in lieu of three weeks of code review.
Legion Code
// An IDE — and a harness — for the AI-augmented developer.
Legion Code is the third flagship: a full IDE, like Cursor or VS Code, plus a harness — the runtime that connects an AI to a human and gives them shared powers. The AI doesn't just suggest. It plans, it runs Secure on your PR before you push, it asks Atlas what each function actually does, it builds with the rest of the Legion stack as its memory. This is the castle entrance: it's how a vibe coder ends up shipping enterprise-grade work.
// Crosses the drawbridge into the castle.
Harness, not autocomplete
A persistent agent that plans, builds, and reflects — not a token-by-token suggestion box.
Native Legion stack
Secure runs pre-PR. Atlas is the memory. Cloud is the canary. Nothing bolted on.
From vibe to shipped
A solo founder writes the feature; Code holds it to the same standard a senior engineer would.
Built on open editor
Forked from a well-known open editor — your shortcuts, your extensions, your muscle memory.
Legion Sight
// See who is visiting your site. Turn anonymous traffic into named people.
Legion Sight is the go-to-market flagship. A lightweight pixel sits in your site header and resolves anonymous visitors against a permissioned identity network — turning "someone from a Fortune 500 looked at pricing" into a named person with a business email and a LinkedIn profile. Resolved visitors flow into a live feed, get auto-tagged against your Ideal Customer Profile, and fan out to Slack, your CRM, or an enrichment tool like Clay. It is the stack pointed outward: the moat tells you your code is sound; Sight tells you who is already at the gate.
// Names everyone who scouts the walls.
Person-level resolution
Anonymous visitor → named person with business email and LinkedIn, scoped to US data subjects.
ICP auto-tagging
Every resolved visitor scored against your Ideal Customer Profile the moment they land.
Live identity feed
A real-time stream of who is on your site right now — not a weekly export.
Push anywhere
Fan identities out to Slack, your CRM, or Clay via webhook and the enrichment API.
Legion Cloud
// Enterprise-grade infrastructure. A pressure-test vessel.
Legion Cloud isn't public. It's the surface where the rest of the stack runs at scale, against real load, with a small set of enterprise users (including us). We learn what breaks before customers do. It's our own dogfood, and a quiet revenue line for the design partners who already have access.
// The water in the moat.
Legion Research
// How developers actually write code in the time of AI.
Legion Research is our in-house research arm. We field surveys, instrument open datasets, and publish findings free. It keeps the rest of the product line honest — the data is what tells us whether the harness is actually helping, whether scans are catching what matters, whether Atlas's spec is one developers want. The flagship publication is the Vibe Code Survey, run annually; the 2026 edition fields in October.
Legion Academy
// Train the next ten thousand developers on the stack.
Legion Academy is a stub for now. The plan: a curriculum-grade training program for individual developers and engineering orgs adopting the Legion stack. Not certifications. Working competence with the harness, the spec, and the moat-building practices. Launch targeted for next year.
