Cognition's Devin for Terminal brings the full autonomous coding power of Devin to your command line. Unlike the browser-based Devin interface, the Terminal version lets you trigger complex engineering tasks from your CLI and continue working — or close your laptop entirely — while Devin executes in the cloud in a persistent session. The key innovation is bidirectional handoff: you initiate locally, Devin Cloud takes over with a persistent execution environment that survives network drops, sleep cycles, and machine switches. This bridges the "last mile" problem of autonomous coding tools — the frustrating requirement to stay connected while a long job runs. Launched April 29, 2026, Devin for Terminal is free to use and signals Cognition's push toward deeper developer workflow integration beyond browser-only interfaces. The clear implication: the future of coding agents isn't a tab you keep open, it's infrastructure that runs in the background.

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
“The 'keep working when you close your laptop' pitch is exactly right. I've lost countless Devin sessions to network hiccups. Persistent cloud-backed execution from my terminal is the architecture I've wanted since day one. This is how async development should work.”
“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.”
“Devin's benchmarks have always been impressive; real-world results sometimes less so. A terminal wrapper doesn't change the underlying model's limitations — it just makes them more convenient to encounter. And Cognition still hasn't fully addressed cost transparency on longer sessions.”
“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.”
“Devin for Terminal is a preview of where all coding tools are heading: invisible infrastructure that executes while you're away. The terminal is the right interface — it meets developers where they already live. Expect every major coding agent to have a persistent CLI within 6 months.”
“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.”
“Terminal tools aren't for most creators — but for technical creatives who build their own tools, persistent agent execution is a genuine unlock. Kick off a refactoring job, go design something, come back to a finished PR. That's a workflow shift.”
“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.”
