Date: 2026-04-04 Core Positioning: We sell insurance, not a framework. Pricing anchored to money saved, not features delivered.
Open Source (Free) → User discovers value
↓
Pro Subscription ($29) → Individual/small team pays for runtime guards
↓
Enterprise ($199+) → Organization pays for team-wide cost control
| Feature | Details |
|---|---|
CLI lambdagent lint |
26 rules, runs locally, unlimited |
| MCP Server (local mode) | 4 tools, runs locally, no network required |
| VS Code extension (basic) | Real-time lint, inline diagnostics |
| GitHub Action (public repos) | PR checks, unlimited |
Python package lambdagent |
Core DSL + compiler + type checker |
| T-Compose type checking | First 2 pipeline levels only |
| Cost prediction | Total cost only (no per-stage breakdown) |
| Parallel safety check | Up to 2 parallel agents |
Why free: This is the acquisition funnel. A developer runs lint, discovers 3 ERRORs, avoids a $5 failed run — and remembers the tool.
| Feature | Free | Pro |
|---|---|---|
| Lint (26 rules) | ✅ | ✅ |
| T-Compose type checking | 2-level pipelines | Unlimited depth |
| Cost prediction | Total cost only | Per-stage breakdown + optimization suggestions |
| Parallel safety | 2 agents | Unlimited |
lambdagent-guard middleware |
❌ | ✅ LangChain / CrewAI / AutoGen |
| Runtime cost circuit breaker | ❌ | ✅ Set budget ceiling, auto-pause |
| Runtime loop detection | ❌ | ✅ Repeated state → alert |
| Cost anomaly detection | ❌ | ✅ Actual vs expected >2x → alert |
| GitHub Action (private repos) | ❌ | ✅ Unlimited |
| Historical analysis reports | ❌ | ✅ Weekly/monthly cost trends |
| Priority bug fixes | ❌ | ✅ |
Pricing logic: $29/month ≈ cost of one failed agent run. Claude Code #38029's $342 incident pays for 11 months of Pro.
| Feature | Pro | Enterprise |
|---|---|---|
| All Pro features | ✅ | ✅ |
| SSO / SAML | ❌ | ✅ |
| Team dashboard | ❌ | ✅ Org-wide agent cost/failure overview |
| Custom lint rules | ❌ | ✅ Enforce internal standards |
| On-premise deployment | ❌ | ✅ Code stays in your network |
| SLA + priority support | ❌ | ✅ 48h response |
| Audit log | ❌ | ✅ Who changed what config, when |
| Org-level cost ceiling | ❌ | ✅ Total agent budget for entire org |
| API calls | — | Unlimited |
| Custom extractors | ❌ | ✅ Support internal frameworks |
Never price by features. Price by losses avoided.
| Real Incident | Loss | lambdagent Saves | We Charge |
|---|---|---|---|
| Claude Code #38029 (auto-generate 652K tokens) | $342/session | $342 | $29/month |
| Claude Code #34629 (cache bug 28 days) | Thousands of dollars | Thousands | $29/month |
| Claude Code #4095 (1.67B tokens) | $1,000+ | $1,000+ | $29/month |
| AutoGen #108 (blank message loop) | API quota exhausted | Full quota | $29/month |
| Enterprise: 100 agents × $1.74/run × 10 runs/day | $522/day | 40% savings = $209/day | $199/month |
Sales pitch: lambdagent Pro costs $29/month — the price of a single ReAct loop run. It catches all type errors, predicts cost ceilings, and detects infinite loops before execution. A single prompt-cache bug in Claude Code cost users 10-20x for 28 days. lambdagent's cost anomaly detection catches this on the first call.
Free → Pro → Enterprise funnel
Conversion estimates (benchmarked against Snyk/SonarCloud):
Free users: 10,000
Pro conversion: 3-5% → 300-500 × $29/month = $8,700-$14,500/month
Enterprise: Contact sales → 10-20 teams × $199/month = $1,990-$3,980/month
Estimated ARR (mature): $120K - $220K
Pay-per-call REST API for users who prefer not to subscribe:
POST /api/v1/analyze/full
Pricing:
Lint: $0.001/call (nearly free — lead gen)
Type checking: $0.005/call
Cost prediction: $0.005/call
Parallel safety: $0.005/call
Full analysis (4-in-1): $0.01/call
Example: CI/CD calls once per PR
100 PRs/month × $0.01 = $1/month (too cheap to matter)
→ API is an on-ramp to Enterprise, not a revenue driver

Paid = server-side computation, continuous monitoring, team collaboration
Free: Paid:
"This config has 3 ERRORs" "This config costs $1.74/run.
Reduce to 3 parallel scanners to
save 40%. Here's the optimized config."
"Type mismatch" "Type mismatch between stage 2-3.
Add a Json→Str adapter.
Here's the auto-generated fix diff."
"Parallel conflict detected" "Over the past 7 days your agents
triggered 12 store conflicts.
Most common key: shared_doc.
Here's the trend chart."
Principle: Diagnosis is free, prescription is paid.
| Product | Analogy | Free Tier | Paid Tier |
|---|---|---|---|
| Snyk (security scanning) | Similar: scan code for vulnerabilities | Open source free | $25/month/developer |
| SonarCloud (code quality) | Similar: static analysis | Public repos free | $14/month+ |
| Datadog (observability) | Similar: runtime monitoring | Limited free | $15/month/host |
| Sentry (error tracking) | Similar: runtime error detection | 5K events free | $26/month |
| LangSmith (LLM observability) | Direct competitor | 5K traces/month | $39/month |
lambdagent Pro at $29/month is below LangSmith ($39) while offering capabilities LangSmith lacks entirely: static type checking, compile-time cost prediction, parallel safety verification, and algebraic law-based optimization.
| Capability | LangSmith | lambdagent |
|---|---|---|
| Runtime tracing | ✅ | ✅ (via TraceHandler) |
| Runtime cost tracking | ✅ | ✅ |
| Static type checking | ❌ | ✅ |
| Compile-time cost prediction | ❌ | ✅ |
| Parallel safety verification | ❌ | ✅ |
| Dead loop detection (compile-time) | ❌ | ✅ |
| Cost anomaly detection | ❌ | ✅ |
| Algebraic optimization | ❌ | ✅ |
| Framework support | LangChain only | LangChain + CrewAI + AutoGen |
LangSmith tells you what happened after you spent the money. lambdagent tells you what will happen before you spend anything.

| Risk | Mitigation |
|---|---|
| LangChain/CrewAI add their own type checking | Our formal basis (λA calculus) is deeper; they'd need years to match. Also we're framework-agnostic — we check ALL frameworks, not just one. |
| Users don't want to pay for static analysis | Anchor to real incidents ($342 session, 10-20x cost bug). Free tier ensures we never lose users who won't pay — they still spread the word. |
| Enterprise sales cycle too long | Start with bottom-up adoption: developers install free CLI → tell their team → team asks for Enterprise. Not top-down sales. |
| Open source competitors fork our code | Our moat is the theoretical foundation (3 papers) + framework extractors (reverse engineering each framework). Hard to replicate without the λA expertise. |
| LLM costs drop, making cost prediction less valuable | Shift emphasis to safety (type checking, loop detection, parallel safety). Cost is one of four value propositions, not the only one. |
Free lint is the hook, paid runtime guard is the line, enterprise dashboard is the net. Let developers experience "knowing a pipeline will crash before spending a dollar" for free, then charge for "catch problems at runtime" and "team-wide cost control."
