## Future AGI

Future AGI packages the full loop of building reliable AI agents: simulate, iterate, evaluate, optimize and monitor. On the simulation side it generates synthetic datasets and scenarios using personas, so you can stress-test a support bot or a voice agent against hundreds of conversation branches before a single real user is involved. Outputs are scored on dimensions such as factuality, relevance, safety and completeness, and failing runs are surfaced in an error feed you can triage.

Evaluation is deliberately flexible. Simple heuristic metrics such as BLEU, ROUGE and regex checks are free and unlimited, while code-based evaluators and LLM-as-judge models run through a shared AI credit pool. Bring-your-own-key judge calls cost nothing on the platform. The same credits power the AI gateway and guardrails: 15 built-in rule-based checks for PII, secrets and patterns are always free, and an ML moderation model handles toxicity, injection and content safety.

On the operations side the platform offers distributed tracing with spans, sessions and agent graph visualisation, custom dashboards and alerting to Slack or email. An AI gateway adds routing across 15+ providers, auto-failover, semantic caching and cost tracking. Datasets and prompt/agent workbench features stay free regardless of plan, and the free tier includes 50 GB of trace storage, 2,000 AI credits, 100,000 gateway requests, 1M text simulation tokens and 60 minutes of voice simulation per month.

**Pricing & Plans:** Usage-based pricing with a generous free tier on every product. Free includes 50 GB tracing, 2,000 AI credits, 100K gateway requests, 100K cache hits, 1M text simulation tokens and 60 voice-simulation minutes monthly. Overage rates start around $2/GB storage, $10 per 1,000 AI credits, $5 per 100K gateway requests, $2 per 1M text simulation tokens and $0.08 per voice-simulation minute, with volume discounts. Higher annotation tiers (Boost ~$250/mo, Scale ~$750/mo) exist for heavier review workflows; enterprise and startup plans are available on request.

- **Simulations and synthetic data:** Generate personas, scenarios and synthetic datasets to stress-test text and voice agents across many conversation branches before launch.
- **Multi-mode evaluation:** Combine always-free heuristic metrics, code evaluators and LLM-as-judge scoring, including agentic evaluators that localise errors in RAG and tool calls.
- **AI gateway and guardrails:** Route traffic across 15+ LLM providers with load balancing, failover and caching, plus 15 built-in rule-based guardrails and ML content moderation.
- **Observability and monitoring:** End-to-end traces, sessions, agent graphs, custom dashboards and alert monitors give real-time visibility into production behaviour.
- **Open-source components:** Parts of the stack are published on GitHub under Apache 2.0, so teams can self-host and inspect the evaluation infrastructure.

**Strengths:** Very generous free tier that most small teams can run on without paying; Covers the whole lifecycle: simulation, evaluation, gateway, monitoring; Free unlimited heuristic evaluations and BYOK judge calls with no platform fee; Open-source Apache 2.0 components plus region choice (US/EU) for data residency

**Limitations:** Credit-based pricing across many modules can be hard to forecast at scale; Interface and module structure are dense, with a learning curve for newcomers; Advanced annotation capacity sits behind separate Boost/Scale plans

## LangWatch

LangWatch started as an open-source LLM observability tool and has grown into an end-to-end platform for AI platform teams. The tracing layer is OpenTelemetry-native, so agents built with LangChain, LangGraph, CrewAI, Mastra, Pydantic AI or the Vercel AI SDK send spans without a rewrite. Traces carry tokens, cost and cache data, can be explored as waterfalls, flame graphs, topology or sequence diagrams, and are searchable through saved views, plain-language search and automatic topic clustering.

On top of tracing, LangWatch layers evaluation and testing. Teams can score a single output or a whole conversation with an LLM judge, custom code or a full workflow; run evals from a notebook or the shared UI; and evaluate live production traffic. Agentic testing simulates realistic text and voice users that push the agent turn by turn, while red-teaming runs adversarial simulations to surface jailbreaks, policy breaks and unsafe tool calls before users do.

More recent additions target day-to-day operations: an AI Gateway routes every provider call (OpenAI, Anthropic, Google, Bedrock, Mistral) through one endpoint with per-person, per-team and per-customer budgets and minimal overhead; coding agents such as Claude Code and Codex can be brought onto the same observability standard with a single command; and Langy turns a product manager's plain-language goal into a scenario test plan and then into pull requests. LangWatch offers cloud, self-hosted and hybrid deployments and states ISO 27001 certification, GDPR compliance and EU data residency options.

**Pricing & Plans:** LangWatch publishes a dedicated pricing page alongside a book-a-demo path, with plans that scale from individual and team use to enterprise. Self-hosting is available as an option, and the project has open-source roots, but specific tier prices, seat limits and credit allowances should be confirmed on the vendor's current pricing page.

- **OpenTelemetry-native tracing:** Full GenAI spec support means traces from LangChain, LangGraph, CrewAI, Mastra, Pydantic AI, the Vercel AI SDK and any OTel-compatible stack land in the same view, with tokens, cost and cache accounted per span.
- **Offline and online evaluations:** Score single outputs or entire conversations with an LLM judge, custom code or a workflow, run evals from a notebook or UI, and evaluate live production traffic in real time.
- **Agentic testing and simulations:** Simulated text and voice users push agents turn after turn in realistic scenarios, runnable locally and in CI, with tools, skills and MCP servers traced and mockable.
- **AI Gateway and budgets:** Route OpenAI, Anthropic, Google, Bedrock, Mistral and other providers through one endpoint using your own keys, with budgets per person, team and customer and around 11 microseconds of overhead.
- **Red-teaming and prompt management:** Adversarial simulations probe for jailbreaks and unsafe tool calls, while prompts are versioned, deployed and A/B tested as code with full history and GitHub sync.

**Strengths:** OpenTelemetry-native with broad framework support, so adoption usually requires no rewrite; Combines tracing, evals, agentic testing, gateway and red-teaming rather than covering only one layer; Self-hosted, hybrid and cloud deployment options plus ISO 27001 and GDPR statements for security reviews; Open-source roots and an active community make the tracing layer approachable for individual developers

**Limitations:** The expanding surface area (gateway, Langy, coding-agent tracking) means more to configure and learn; Enterprise-grade governance features require a sales conversation rather than self-serve signup; Value depends on instrumenting your stack; teams without tracing in place will need setup work
