Local context for AI coding agents.
Tessra gives Claude Code, Codex, and Cursor structured repository context to understand symbols, dependencies, and impact radius before changing code — with production-optimized support today for Angular, Django, and Flutter.
Internal benchmark results.
Controlled benchmark on a real-world Angular payment component — multiple payment gateways and injected services. In internal testing, Tessra helped lower-cost models outperform premium models alone on real refactor tasks. April 2026.
AI agents are reading code but not understanding it.
Today's coding agents work file-by-file. On a 200K-line repo, that means tokens spent, context lost, and confidence destroyed.
Too many tokens
Agents flood context windows with files they don't need. Cost balloons, signal drops, latency creeps up.
Shallow understanding
Models read snippets but miss relationships. They guess at conventions and invent APIs that don't exist.
Risky refactors
Changing a function feels like a coin flip. No one — human or agent — knows what touches what across the repo.
Slow onboarding
New devs and new agents both spend days learning where things live. Tribal knowledge stays stuck in heads.
From raw repository to impact-aware context.
A local MCP server that indexes your codebase once and answers every agent query with structure, not raw text. Best results today on Angular, Django, and Flutter repositories.
Point Tessra at your repo
One command. Tessra detects your git root, registers it if needed, and activates it for the current session.
tessra here Your agent queries what it needs
Start the local MCP server and let your agent ask for symbols, callers, and impact radius — structured, not raw text.
tessra mcp Ship with confidence
Your agent has the context a senior engineer would have. Impact is known. Risk is surfaced. Changes land clean.
From question to safe change.
Tessra turns a single agent question into a confident engineering decision — impact, risk, and the path forward, before a line of code changes. The agent gets the result, not the graph.
This structure is computed internally — your agent receives only what matters.
This change touches billing, checkout, and the Stripe webhookhandler. Refactor should preserve the existing webhook payload structure — downstream consumers depend on field order and types.
Senior engineering judgment, served as context.
Tessra doesn't replace your agent — it gives it the same situational awareness a senior engineer would have on day 800 of the project.
Ship AI changes without breaking prod
Every refactor comes with an impact radius. Know what breaks before you push — across files, services, and tests.
Spend 15× less on tokens
Tessra returns only what the agent needs: symbols, signatures, related callers. Stop paying to re-parse the same files.
Your code never leaves your machine
Indexes run locally. No cloud. No uploads. No external APIs. MCP-native — plugs into any compatible agent.
First-class support for Angular, Django, and Flutter
Tessra is currently optimized for these three stacks, with deeper framework-aware context for safer refactors and better agent decisions.
Your code never leaves your machine.
Tessra runs locally. No uploads. No cloud indexing. No external processing. Your code stays where it belongs.

"Tessra made our Angular codebase approachable for Claude. The impact radius alone saved us from two bad refactors."
"We switched from GPT-4 to Haiku + Tessra. Same quality, drastically lower cost."
