What you write is what your agent does. Your spec defines behavior, inputs, and outputs. No frameworks, no SDKs, just words.
Every agent ships with a built-in test harness. Define expected outputs, run your suite on save, and catch regressions automatically.
Previously required: Braintrust, Promptfoo, custom eval scripts
Every spec change is versioned, diffed, and reversible. Engineers get stable APIs while non-engineers update agent logic through approval workflows, without redeploying or managing prompts in a separate tool.
Previously required: PromptLayer, HumanLoop, Custom Pipelines, Manual Versioning
Every agent can be exposed as a strictly typed REST API the moment you save it. Logic auto-generates docs, input forms, and a shareable web UI from your spec.
Previously required: Custom frontend, API documentation tools, Swagger/OpenAPI
Logic routes each request across OpenAI, Anthropic, Google, and Perplexity, matching fast models to simple tasks and frontier models to complex reasoning. Failover is automatic.
Previously required: OpenRouter, Martian, Custom routing logic
Every execution is logged with full context: inputs, outputs, model reasoning, latency. When something breaks, you know exactly where and why.
Previously required: LangFuse, LangSmith, Custom Logging

Garmentory, an online fashion marketplace, scaled from 1,000 to 5,000+ products moderated daily and had their best financial quarter in company history.
Read the full story“A year ago, we were using almost no AI. Today, we're exploring using it in every part of our business. Logic made that jump possible.

Sunil Gowda
CEO, Garmentory
“On those more complex POs, Logic takes my work from half an hour down to two minutes. That's a massive time saver.
