Logic is a spec-driven agent platform that collapses the fragmented AI toolchain into a single system. Write your agent's behavior in plain English, and Logic auto-generates a typed REST API complete with inline test cases, version control with diff tracking, rollback, and execution logging — no framework setup or infrastructure build required. The generated API is immediately production-grade with SOC 2 Type II and HIPAA certification and a 99.9% uptime SLA. What makes Logic different is what it replaces: most teams stitching together AI agents end up managing PromptLayer for versioning, Braintrust for evaluation, LangFuse for logging, and Swagger for API docs. Logic consolidates all of that. Model routing is automatic — it picks between OpenAI, Anthropic, Google, and Perplexity based on task complexity, cost, and latency. Agents can connect to external tools via MCP, query a built-in knowledge library, and process CSV batches in parallel. The non-engineer story is compelling too: because the source of truth is a plain English spec rather than code, product managers and ops teams can update agent behavior without breaking the API contract. Logic deployed to the top of Product Hunt's charts today, signaling that the 'spec as code' pattern is resonating with teams burned by brittle prompt management.

Rocky
Rust-compiled SQL for data pipelines: branches, lineage, AI intent layer

Rocky is a Rust-based SQL transformation engine that brings software engineering discipline to data pipelines. Where tools like dbt gave data teams a version-controlled workflow, Rocky goes further: type-safe compile-time SQL, column-level lineage visualization, git-style branches for isolated testing, and a built-in AI intent layer that stores your purpose as metadata alongside the code. The branching feature is the standout — you can create a branch, run it against an isolated schema, inspect the results, then drop or promote. The column-level lineage shows the full downstream blast radius before you ship a change, tracing any single column back through every aggregation and join to its source. This is the kind of visibility that prevents the "who broke the revenue dashboard" post-mortems that happen in every data team. The AI intent layer is genuinely novel: it stores what a model is supposed to do as metadata, so AI can later explain models, auto-update them when upstream schemas change, and generate tests based on the original intent. Rocky integrates with Dagster via an official plugin and supports DuckDB for local development with no credentials required. With Hacker News coverage and a Rust-native architecture, it's positioned as the data pipeline tool for engineering-forward teams who are tired of YAML-based transformations.
Reviewer scorecard
“Eliminating the PromptLayer + Braintrust + LangFuse + Swagger stack into one product is genuinely useful. Auto-generated typed APIs with regression detection on every spec edit is what I want — I don't want to maintain that infra myself. MCP integration is the right call for tool connectivity.”
“Compile-time type safety for SQL is the feature I've wanted for years — catching type mismatches before the pipeline runs instead of finding out when a dashboard breaks at 9am. The column-level lineage alone justifies the migration cost for any team managing complex pipelines.”
“Platform lock-in is the real risk here. You're encoding your agent logic in their proprietary spec format, which means migration is painful if pricing changes or the product gets acquired. The 'plain English spec' sounds great until your requirements are complex enough to need real code — then you're hitting the ceiling of what their abstraction can express.”
“dbt has a massive ecosystem, hundreds of integrations, and years of community knowledge — migrating to Rocky means giving all that up for a Rust tool with a small user base. The AI intent layer sounds cool but 'stores intent as metadata' is vague; in practice this is probably just comments with extra steps.”
“Spec-driven development is the right abstraction layer as agents proliferate. When non-engineers can update agent behavior in plain English without involving a developer, the deployment velocity for AI systems increases by an order of magnitude. Logic is betting on the right future — the question is whether they build a moat before the big platforms copy the pattern.”
“Data pipelines are the next frontier for AI-assisted maintenance, and Rocky's intent metadata approach is ahead of the curve. When AI can auto-reconcile pipelines after schema changes because it knows what each model was meant to do, that's a qualitative shift in how data infrastructure gets maintained.”
“Being able to update an AI agent's behavior in plain English without filing a ticket with engineering is huge for content operations teams. I can see this being the way marketing and editorial teams manage their own AI workflows without needing to understand prompt engineering. The free tier makes it worth experimenting with.”
“Rocky is clearly built for engineering-heavy data teams — the VS Code extension, compile-time guarantees, and Dagster integration signal a developer-first product. For data analysts and business intelligence folks who just need their transforms to work, the learning curve is steep.”
