NeuralBridge Goes Open Core: Free + Pro, Same SDK, Your Choice

#opensource #llm #typescript #python

The Short Version

NeuralBridge SDK is now Open Core. The entire SDK remains Apache 2.0 — free to use, modify, and distribute. If you need unlimited providers, L3 self-healing, or flywheel persistence, grab a Pro license. If not, nothing changes.

Why Open Core?

After watching the AI infrastructure space for the past year, we realized something: the teams that need self-healing most are often the ones with the tightest budgets — solo developers, early-stage startups, open-source projects. Open Core is the cleanest middle ground.

Tier Price What You Get
Free Apache 2.0 Core engine, 2 providers, L1 retry, circuit breaker, rate limiter, basic flywheel
Trial 7-day free All Pro features unlocked
Pro $99/year Unlimited providers, L3 heal, flywheel persistence, checkpoint, telemetry export
Professional $499/mo + Custom diagnoser, team dashboard, priority support
Enterprise $1,499/mo + Audit log, on-prem deploy, SLA 99.9%

What Stays Free

Everything you already use — the MAPE-K self-healing engine, circuit breaker, rate limiter, bulkhead, diagnoser, basic flywheel, checkpoints, streaming — stays Apache 2.0. Zero feature removal.

What Pro Unlocks

Unlimited providers — Free caps at 2 providers. Pro removes the limit entirely.

L3 healing — Free gives you L1 (retry). Pro adds L2 (downgrade) and L3 (full failover with learned routing).

Flywheel persistence — Pro persists learned failure patterns across restarts. The SDK gets smarter over days, not just per-session.

One Line to Activate 

// Free — nothing changes
import { NeuralBridge } from 'neuralbridge-sdk';

// Pro — just add a license key
const nb = new NeuralBridge({
  providers: ['openai', 'anthropic', 'deepseek', 'google', 'groq', 'nvidia'],
  licenseKey: process.env.NEURALBRIDGE_LICENSE_KEY,
});
Enter fullscreen mode Exit fullscreen mode

CLI 

npx nb-doctor pro status
npx nb-doctor pro activate NB-PRO-XXXX
export NEURALBRIDGE_LICENSE_KEY=NB-PRO-XXXX
Enter fullscreen mode Exit fullscreen mode

Why Pay?

If you're running one or two providers in dev, the free SDK works great. If you're running 5+ providers in production, the cost of one incident exceeds the Pro license by orders of magnitude.

What About Python?

Same model. Python SDK v5.2.11 already has the licensing infrastructure. Free works out of the box.
