Works with your stack

Lineman runs inside Claude Code and works across the languages and platforms you already use.

The Lineman team

Lineman lives inside Claude Code, not beside it. It installs as a plugin and sits quietly on the data-heavy tool calls your model already makes: file reads, build and test output, code search, web fetches. Instead of the raw dump, it hands back the parts that matter. Because it works at the tool layer, it doesn't care what you're building in.

Whatever language your project happens to be in, the work Lineman does is the same. A secondary model condenses bulky tool output before it reaches your primary model, so you spend context on reasoning rather than on scrolling. That's what keeps it language-agnostic by design.

One plugin, every language you already use

Lineman has no per-language setup. The same install covers the stacks teams ship every day:

  • TypeScript, JavaScript, Node.js and the web frameworks on top: React, Next.js, Vue, Angular
  • Python, Go, Rust for services, tooling, and systems work
  • Java, Kotlin and Swift across server and mobile
  • C, C++, C# for performance-critical and .NET codebases
  • Ruby and PHP for web applications

A monorepo that mixes several of these is where Lineman earns its keep. A single large file read, a noisy test run, or a wide grep costs the same context whether it's Rust or Ruby, and Lineman compresses all of them the same way.

It rides on the tools, not the syntax

Lineman doesn't parse your project to "understand" a particular language. It intercepts the tool calls (reading a file, running a command, searching the tree, fetching a page) and returns a tighter result. New frameworks, generated code, config files, lockfiles, and logs all benefit without being special-cased. If Claude Code can call the tool, Lineman can compress what comes back.

Runs where Claude Code runs

The plugin is the same on macOS, Linux, and Windows. Every step runs inside a Claude Code session, so there's nothing platform-specific to configure. Install it once per machine, authenticate, and your next large file read or build triage goes through Lineman automatically.

Support for more editors and assistants is on the roadmap. For now, Claude Code is the home, and that's where the savings show up across whatever you happen to be working in.

See the savings on your stack

The savings come from how much data-heavy work you do, not which language you do it in, so the best way to size them is against your own workload. The savings calculator on the homepage estimates what Lineman would trim from your real usage, and the full method is on the benchmarks page. Pricing for individuals and teams is on the pricing page, and you can start a trial without a card.

How to Reduce AI Coding Spend With Log Compression in 7 Steps (2026)

Build logs and file reads account for over half of most AI coding bills. The tokens aren't reasoning about your code—they're re-reading the same data, turn after turn. AI infrastructure cost optimization starts by cutting the bytes your model never needed to see in the first place.

How to Summarize Large Codebases for AI Agents in 7 Steps (2026)

Quick Guide: How to Summarize Large Codebases for AI Agents in 7 Easy Steps Parse Code with Abstract Syntax Trees: Extract meaningful structure from source files using AST parsers that preserve semantic boundaries. Chunk Code at Symbol Boundaries: Split files at function, class, and module boundaries instead of arbitrary line counts. Generate Semantic Embeddings: Convert code chunks into vector representations that capture meaning, not just syntax. Build a Vector Index for Retrieval: Store embeddings in a vector database for fast similarity search across your codebase. Implement Selective Context Retrieval: Query only the relevant code chunks based on the agent's current task. Compress Tool Output Before Context Injection: Use Lineman to automatically compress file reads and logs before they reach your AI agent's context window. Cache and Deduplicate Repeated Reads: Track what the agent has already seen to avoid re-injecting identical content. How to Help AI Agents Understand Large Repositories Without Full-Context Dumps 1. Parse Code with Abstract Syntax Trees The first step is treating code as structure, not text. AST parsers read your source files and produce a tree that represents the actual program logic: functions, classes, imports, and their relationships.

9 Claude Instruction Audits for Leaner DevOps

System instructions in Claude coding agents carry a hidden cost. Every token in your CLAUDE.md file is re-sent on every single turn, whether you need it or not. For DevOps teams running automated pipelines, test triaging, and infrastructure tasks, that overhead compounds across hundreds of daily sessions.
