Making food growing approachable, affordable, and accessible because everyone deserves to know how to feed themselves and their community.
An AI advisor that knows your soil and weather. A knowledge base built by real growers. Smart sensors you build yourself for the cost of a pizza. Cooperative soil labs so communities can test their own land. All open source. All free. Runs on a Raspberry Pi.
Most people are disconnected from how their food grows. Kallyx changes that. Not through lectures. By making growing genuinely fun and rewarding. Start with a single pot of basil. We'll be there every step.
This isn't a chatbot that Googles things for you. The Kallyx advisor pulls your real sensor readings, checks your local weather forecast, looks up your soil analysis results, and searches the knowledge base before it says a word. Every recommendation traces back to actual data.
Ask it "Why are my tomato leaves curling?" and it checks your soil moisture (45%), your weather (32mm rain on Tuesday), your last soil test (nitrogen at 18 ppm, below the 25-50 ppm adequate range for tomatoes), then tells you exactly what happened and what to do about it.
It cites its sources. It tells you how confident it is. When it doesn't know, it says so and tells you to ask a human.
Workflows from seed to harvest. Each step tells you what to do, when, and why. Track progress with checkboxes and reminders. "Time to thin your carrots" shows up exactly when you need it.
Crop scoring adjusted for your zone, season, and soil type. Fertilizer plans optimized for what your soil actually needs, not what the bag says. Trend forecasting that catches problems before your plants show symptoms.
Kallyx scales from a first-timer growing herbs on a windowsill to a commercial operation managing hundreds of acres. Same platform, same tools, same open data. You don't outgrow it.
Growing knowledge is scattered across blogs, forums, and paywalled apps. Kallyx pulls it all into one open, intelligent system that anyone can access, no matter where they are or what device they're on.
Plant profiles, companion planting charts, pest identification, seasonal calendars, and growing guides. All of it searchable, categorized, and explained in plain language. Every technical term has a glossary tooltip that breaks it down without talking down to you.
The AI advisor links directly into the knowledge base. When it tells you about nitrogen deficiency, you can click through to the full article, see the science, read the sources. Knowledge isn't just delivered, it's explorable.
Available in 12 languages: English, Spanish, French, Portuguese, Swahili, Hindi, Bengali, Arabic, Chinese, Amharic, Yoruba, and Hausa. There's a community translation workflow so anyone can contribute translations for their language.
Not every garden has Wi-Fi. Not every farmer has reliable internet. Kallyx works offline with local data caching and edge processing. When connectivity returns, it syncs automatically with conflict resolution. No data lost, no overwrites, field-level merge.
SMS and WhatsApp alerts reach people where web push can't. "Your soil moisture dropped below 30%" arrives as a text message in Swahili at 6am, before the farmer walks to the field.
The knowledge base isn't static. Community members contribute articles, translations, and local growing tips. The AI enriches entries with cross-references, related topics, and plain-language summaries of research papers. The best knowledge usually comes from the experienced grower next door. Kallyx just makes it findable.
The experienced gardener next door has decades of knowledge. The community garden down the street has spare seeds. Kallyx connects those people. Mentors to beginners, neighbors to neighbors, growers to growers.
Professional soil testing costs $25-75 per sample through a university extension. Most small growers skip soil testing entirely. Without real data, fertilizer choices are mostly guesswork.
Kallyx lets cooperatives share soil testing equipment and track samples through the full pipeline: collection, transport, lab analysis, results. Chain-of-custody logging at every step. One community lab can test hundreds of fields. Results show 14+ elements against Mehlich-3 reference ranges, with year-over-year comparison so you can see if your amendments are actually working.
On the R&D track, we're building open-source control software for MP-AES spectrometers. That's the same lab equipment commercial soil testing facilities use. The hardware costs thousands, but the software to run it shouldn't cost $50,000. Our framework handles multi-point calibration, drift correction, NIST verification, and QA/QC validation with the same rigor as commercial instruments.

A catalog of downloadable 3D-printable designs. Sensor housings, mounting brackets, irrigation fittings. Print settings, bill of materials, and assembly guides included. One person with a 3D printer can supply sensor enclosures for an entire community garden.
Kallyx is built for real people growing real food. Backyards, balconies, community gardens, small plots, commercial scale. Self-hostable, runs on a Raspberry Pi, and your data is yours.

Most commercial sensors require subscriptions for cloud access to your own data. Kallyx is self-hosted. No subscription, no data harvesting, and you own everything.
Irrigation based on real soil moisture with rain delay. LED grow lights scheduled per crop and growth stage. Fertigation with PID control and automatic safety shutoff. All of it runs on ESP32 edge controllers. Your plants keep growing even when your internet doesn't.
Organizations, sites, and zones in a hierarchy. Owner, admin, operator, and viewer roles. API key auth for integrations. Stripe billing with a free tier. Works for a solo gardener or a cooperative with 500 members.
Live sensor readings via SSE. Historical charts with custom time ranges. Zone-based site maps. Alert thresholds with multi-channel notifications. CSV and JSON export. Dashboard updates without refreshing.
Everything in Kallyx is a REST endpoint. 80+ endpoints across 17 modules. FastAPI with auto-generated OpenAPI docs.
