The integration platform that writes itself

Fyrn replaces MuleSoft, Boomi, and Zapier with a single AI-first platform. Describe what you need, deploy it, and let self-healing handle the rest.

Build

Prompt to production config

Describe what you need in plain English. Fyrn's AI generates a complete flow configuration with connector auth, field mapping, and error handling. The output is a deterministic YAML config, not a black box.

20+ Transform Functions

coalesce, to_integer, lookup, split, join, regex_replace, round, hash, and more. Chain transforms with pipes for complex data manipulation.

Compound Conditions

AND/OR/NOT logic for routing and filtering. Route messages to different targets based on complex business rules, all declared in YAML.

Lookup Tables & Templates

Lookup tables for value translation — country codes, SKU mapping, currency conversion. Start from templates or let AI generate configs from scratch.

Custom Adapters

Write JavaScript adapters with AI-assisted generation. Sandboxed execution for internal APIs, business logic, or data transforms that go beyond the DSL.

Generated config with lookup tables & compound conditions

hubspot-to-salesforce-leads.yaml

name: hubspot-to-salesforce-leads
trigger:
  connector: hubspot
  event: contact.created
steps:
  - transform:
      map:
        first_name: "{{ trigger.firstname }}"
        last_name: "{{ trigger.lastname }}"
        email: "{{ trigger.email }}"
        country: "{{ trigger.country | lookup('country_codes') }}"
  - filter:
      condition:
        and:
          - "{{ trigger.email | is_not_empty }}"
          - not: "{{ trigger.email | ends_with('@test.com') }}"
  - deliver:
      connector: salesforce
      action: lead.create

Run

Deterministic runtime. Self-healing when APIs drift.

AI is only used at config time — never in the hot path. Your flows execute on a deterministic runtime with predictable performance. When APIs change, self-healing detects drift, diagnoses the impact, and auto-fixes mappings with confidence scoring.

Self-Healing Engine

Continuous schema monitoring. Drift detection. AI diagnosis with confidence scoring. High-confidence fixes auto-deploy. Low-confidence changes get flagged for review.

Deduplication

Redis-backed dedup with configurable key and time window. Prevent duplicate processing from webhook retries or at-least-once delivery.

Message Ordering

Sequential delivery with ordering keys. Guarantee processing order for events that depend on each other — inventory updates, account state changes.

Aggregation Windows

Time-based or count-based windows with grouping. Batch order line items, aggregate metrics, or collect events before forwarding.

Self-healing event log

self-healing-event.yaml

# Detected: Stripe API v2024-12 schema change
event: schema_drift
connector: stripe
change_type: field_rename
field_change:
  before: unit_amount
  after: amount_per_unit
analysis:
  semantic_match: true
  type_compatible: true
  confidence: 97%
action: mapping_updated
status: auto_fixed

Orchestrate

Multi-flow pipelines with built-in reliability

Compose flows into pipelines. Fan out to multiple targets. Run multi-step transactions with automatic rollback. All orchestrated declaratively in YAML.

Flow Chaining

Emit to child flows with correlation ID tracking. Build modular pipelines where each flow handles one responsibility.

Fan-Out Routing

Multi-target delivery with per-target conditions. Route the same event to different destinations based on business logic.

Saga Pattern

Multi-step transactions with compensation. If step 3 fails, steps 1 and 2 automatically roll back. Declare the happy path and the compensation path in YAML.

Batch Processing & Published APIs

CSV upload with partial failure handling and per-record status. Expose flows as versioned, documented API endpoints with consumer keys and rate limiting.

Flow chaining, fan-out, and saga in one config

order-orchestration.yaml

name: order-orchestration
trigger:
  connector: shopify
  event: order.created
steps:
  - emit:
      flow: inventory-check
      correlation_id: "{{ trigger.id }}"
  - fan_out:
      targets:
        - flow: erp-sync
        - flow: fulfillment-notify
          condition: "{{ trigger.total_price > 100 }}"
  - saga:
      steps:
        - action: payment.charge
          compensate: payment.refund
        - action: inventory.reserve
          compensate: inventory.release

Observe

See everything. Debug anything.

Every flow gets a detail page with tabs for Overview, Pipeline, Messages, Alerts, Config, and History. Centralized message log with cross-flow correlation search means you can trace any event across your entire integration landscape.

Pipeline Visualizer

See your flow's execution plan as a visual directed graph. Identify bottlenecks and understand data flow at a glance.

Message Traces

Step-by-step timeline for every message. See exactly what happened at each transform, filter, and delivery step.

Centralized Log

Cross-flow correlation search. Find every message related to a single order, customer, or transaction across all your flows.

Alerting

Slack, email, and webhook channels with configurable cooldown. Get notified on failures without alert fatigue.

Secure

Field-level security. No afterthought.

Security is declared in your flow config, not bolted on. PII masking, encryption, and stripping at the field level. Outbound rate limiting per connector. Payload size limits with automatic chunking. Full audit trail for every message.

Security config — declared alongside your flow

security-policy.yaml

security:
  pii:
    email: mask     # j***@example.com
    ssn: strip       # removed entirely
    phone: encrypt  # AES-256 encrypted
  rate_limit:
    connector: stripe
    strategy: token_bucket
    max_per_second: 25
  payload:
    max_size: 5mb
    chunking: auto

Developer Experience

Your terminal. Your workflow.

Everything runs through the CLI. Generate flows from natural language, deploy, check status, tail logs, manage lookup tables, and export/import bundles. Configs are YAML files that live in Git.

fyrn login, generate, deploy, status, logs

fyrn lookup for managing lookup tables

fyrn export / import for CI/CD bundles

Git-native version control — rollback with git revert

$ fyrn generate "Sync Stripe invoices to NetSuite"
✓ Generated stripe-to-netsuite.yaml

$ fyrn deploy --env production
✓ Deployed 1 flow to production

$ fyrn status --all
stripe-to-netsuite  active  99.8%

$ fyrn logs stripe-to-netsuite --tail
12:34:01 OK  invoice.created → netsuite

$ fyrn export --bundle v1.2.0
✓ Exported bundle: fyrn-v1.2.0.tar.gz

Architecture

AI generates. Deterministic runtime executes.

The AI is only used at config time — never in the hot path. Your flows execute on a deterministic runtime with predictable performance, retries, and circuit breakers.

Config Time

AI Generation Layer

NLP to YAML compilation. Schema inference. Mapping generation. 20+ transform functions. Runs once at config creation, not per-request.

Runtime

Deterministic Execution

YAML configs execute on a predictable runtime. Dedup, ordering, aggregation, rate limiting, circuit breakers. No AI in the hot path.

Background

Self-Healing Monitor

Continuous schema monitoring. Drift detection. Auto-fix with confidence scoring. Human escalation when needed.
