What powers AtmaSarathy

Every tirtha has a source. Here is ours — the five elements that carry your inquiry from heart to screen, and what it costs to keep the lamp lit.

"Sarvasya chaham hridi sannivishto" — I am seated in the heart of all beings.
Bhagavad Gita 15.15 · The source behind the source
The five elements

Panchaboota infrastructure

In Sanatana cosmology, all creation arises from five elements — Prithvi, Jal, Agni, Vayu, Akasha. AtmaSarathy's technical stack maps naturally to these five. This is not metaphor for its own sake; it is a reminder that technology, like matter, is a vehicle for consciousness.

Supabase
The ground beneath everything. Stores every user, every conversation, every message, every feedback signal. Row-level security ensures your data stays yours alone. Mumbai region — your words never leave India.

💧 Jal · Water The Flow जल
Resend + Custom SMTP
Water flows to where it is needed. Transactional emails carry the sacred link — account verification, password reset — delivered from noreply@atmasarathy.com. Nothing more, nothing less.

🔥 Agni · Fire The Intelligence अग्नि
Anthropic Claude
Fire illuminates. Claude Sonnet powers authenticated seekers; Claude Haiku serves guest queries. Prompt caching on the 3,400-token system prompt reduces cost and latency. The Sarathy's wisdom runs on Agni.

🌬️ Vayu · Air The Delivery वायु
Vercel Edge
Air carries sound to the ear. Vercel's edge network delivers AtmaSarathy to your device — serverless functions handle every API call, CDN caches every static asset. Invisible when it works; Vayu always is.

Akasha is the witnessing space — the container in which all else exists. atmasarathy.com is the name by which seekers find the tirtha. DNS routes every request to its right destination.

The cost ledger

AtmaSarathy is free. It shows no ads. It sells no data. Here is what it costs to run — openly, without mystification. This is what dharmic transparency looks like in the age of software.

Why we show this

Most platforms obscure their costs to justify their pricing or their advertising. AtmaSarathy is different. The seeker deserves to know what sustains the lamp. These are real numbers, not rounded approximations. The AI inference cost — Agni — is the only variable cost. Everything else is fixed or free at this scale.

Growth economics

What scaling costs

Because Agni is the only variable cost and everything else is free at early scale, the economics are unusually clean. Here is what three stages of growth look like.

Phase 2 — now

Estimates assume 70% authenticated (Sonnet) / 30% guest (Haiku) split, 5 conversations per user per month avg, 85% prompt cache hit rate. Supabase and Vercel tier upgrades triggered at ~500 and ~5,000 MAU respectively. All costs in INR at ₹84/USD.

The dharma-economics pledge

AtmaSarathy will never monetise through advertising, data sale, or dark patterns. The moment ads enter a space of inquiry, they contaminate it. The moment data is sold, the seeker becomes the product. Neither is compatible with dharma.

When the cost of running AtmaSarathy exceeds what the founder can sustain personally, the community will be told plainly — and given the choice to sustain it together through voluntary contribution, not coercion.

Should AtmaSarathy ever invite dakshina, it would be an offering, never a price. What is given would go only toward keeping the lamp lit — and whatever flows beyond that need, onward to a dharmic cause. This is the intention held; today, it is simply free.

🚫
No advertisements. Ever.
A space of dharmic inquiry cannot coexist with commercial targeting. This is a design decision, not a marketing position.
🔒
No data sale. Ever.
Your conversations with the Sarathy are sacred. They will never be sold, licensed, or shared for commercial purposes.
📖
Open cost ledger.
This page is updated when costs change materially. You deserve to know what keeps the lamp lit.
🤲
Community before capital.
If voluntary sustenance is ever needed, the community will be asked — not investors whose interests may diverge from yours.
