Developer Experience

Native SDKs for Modern Stacks

Integrate structured tool calling, multi-agent chains, and Anthropic Claude 3.5 Sonnet in under 10 lines of code.

from synapseflow import FlowEngine, ClaudeModel, Tool

# Initialize Anthropic Claude 3.5 Sonnet engine
engine = FlowEngine(
    model=ClaudeModel("claude-3-5-sonnet-20241022"),
    temperature=0.2,
    max_tokens=4096
)

# Define deterministic agent with tools
@engine.tool
def run_code_audit(repo_path: str) -> dict:
    return {"vulnerabilities": 0, "status": "clean"}

agent = engine.create_agent(
    name="SecuritySentinel",
    system_prompt="Audit pull requests and emit structured fix recommendations."
)

# Stream real-time agent execution tokens
for chunk in agent.stream_run("Audit src/auth/jwt.py for token leakage"):
    print(chunk.delta, end="", flush=True)

Architecture & Features

Built for Unyielding Resilience

Designed specifically for autonomous agent pipelines running high-concurrency production workloads.

Low-Latency Streaming

Ultra-lean zero-copy SSE pipeline yielding sub-100ms first-token latency with complete backpressure management.

Deterministic Tool Calling

Strict JSON Schema enforcement that eliminates hallucinated function signatures and enforces parameter typings.

Multi-Agent Coordination

Actor-model orchestration allowing agents to pass memory states, resolve dependencies, and vote on consensus plans.

Local & Cloud Fallback

Dynamically switch queries from cloud endpoints (Claude, Bedrock) to local Ollama/vLLM instances during rate-limits.

Privacy & Air-Gap Ready

Zero telemetry by default. Runs entirely self-hosted within your VPC without sending metadata to third-party collectors.

100% Open Source

Free forever under the Apache 2.0 license. Inspect every line of code, fork the engine, or contribute upstream.

Live Agent Simulation
