LangChain features
- Build agents fast. Start with proven patterns, customize harness, context, memory and model choice.
- Trace-based testing. Debug runs with step-by-step tracing and query complex traces instantly.
- Managed deployments. Deploy long-running agents with serverless or dedicated sandboxes and 30+ endpoints.
- Production monitoring. Online evals, dashboards and alerts track quality, cost, latency and errors.
- Feedback loop engine. Automatically detect issues, diagnose root causes and feed fixes back into evals.
- Governance controls. Enforce cost limits, data redaction and human approval via LLM Gateway.
WBX Sandbox features
- Isolated runtimes. Run code in full Linux microVMs or lightweight WASI modules with hardware or process isolation.
- Budget Guard. Reserve a maximum cost before execution and refuse jobs that would exceed limits.
- Execution receipts. Each run returns runtime, isolation, resource usage, file hashes and actual cost.
- Batch processing. Submit up to 1,000 jobs in one batch with concurrency control and dependency chaining.
- Native MCP integration. Connect via a single URL to ChatGPT, Claude and any MCP client without API keys.
- Fast start for WASM. WebAssembly jobs start in milliseconds, no VM boot time.
- Automatic lifecycle. Handles retries, timeouts, cleanup and sandbox disposal automatically.
- EU-operated servers. Runs on refurbished enterprise hardware located in the EU.
