Products
Templates for individual components, templates for the full stack, or managed as-a-service — Flomisma is infrastructure for builders who want control, not another dashboard framework.
Zero-persistence WebSocket relay
Authenticate with an API key, publish to rooms, subscribe in real time. No disk, no database in the relay path — enforced by ESLint, CI, and container policy. Usage-metered tiers from free to enterprise.
Double-entry ledger as a managed service
Immutable ledger entries, contract state machine, settlement fee calculation, encrypted vault, and invoice generation — exposed as typed HTTP calls. SOC2-adjacent audit trail included. No custody, no fund transmission. Your money moves through your own rails.
Ephemeral pub/sub purpose-built for agent-to-agent communication
All relay tiers support agent-to-agent pub/sub. Zero-persistence WebSocket relay optimized for AI agent traffic. Agents publish events, subscribe to channels, and coordinate in real time. Built on the same battle-tested relay infrastructure — no separate pricing required.
Full marketplace backend — matching, escrow, ledger, and payments
Managed backend that bundles AI Concierge Matching, settlement ledger, escrow, reputation scoring, and credential badges. Launch a vertical marketplace in days, not months. We operate the infrastructure; you own the relationships.
HMAC-signed credentials as a managed service
Issue and verify cryptographically signed credentials via a simple API. Returns public JSON endpoints and SVG badge images. Verifiable without a central database — the HMAC signature is the proof. No credential storage required.
SOC2-adjacent audit trails, drift detection, and reconciliation
Drop-in compliance infrastructure for fintech and healthtech. Hash-chained audit trails, automated drift reconciliation, SOC2 evidence capture, and configurable alerting. Plugs into any Postgres backend via a simple API.
Production starters on Gumroad
Multi-tenant SaaS, settlement ledger, relay starter — buy once, own the code forever. Each template is documentation-complete and security-hardened.
Claude-powered brief parsing and provider matching
Natural language concierge that parses client briefs, matches providers via AI semantic matching, and orchestrates booking packages. Extracted from a production marketplace — works for any vertical.
HMAC-signed verifiable credentials with SVG badges
Cryptographically signed credential verification system. Generates public credential JSON endpoints and tamper-proof SVG badge images. Verifiable without a central database — signature is the proof.
SLA monitoring, rate limiting, and incident detection
Production-grade automation infrastructure: SLA uptime monitoring with status escalation, token-bucket rate limiting per endpoint, security incident detection and logging, and health metrics collection. Grab-and-go for any marketplace backend.
Model Context Protocol for LLM tool execution
Expose your platform to AI agents via the Model Context Protocol (MCP). Includes agent-key authentication, typed tool definitions, and recommendation engine. Agents discover and invoke your APIs as tools — no custom integration code needed.
We run the stack for you
Relay + settlement ledger, provisioned and operated. Single-region for solo devs, multi-region for teams, dedicated for enterprises. You bring your code, we handle the infrastructure.
Relay
The relay only forwards frames. Quotas live in memory for the billing window, then roll up to the portal ledger — never the message body.
