1M token context window for lightning-fast inline code completions

Built with Supermaven?
Let's make sure it's production-ready.

An ultra-fast AI code completion tool with a 1-million token context window that provides inline completions in any IDE. Known for its speed and ability to understand large codebases from a single context window. We help non-technical founders identify and fix the issues AI tools leave behind.

Common issues we find in Supermaven code

These are real problems we see in Supermaven projects during our audits — not hypotheticals.

highBugs

Fast completions accepted without review introduce subtle type errors

Supermaven's speed is its core advantage, but it encourages accepting completions quickly. TypeScript type errors, incorrect function signatures, and wrong argument orders frequently slip through when developers tab-accept completions at high speed.

highSecurity

Security-sensitive code patterns completed without security review

In security-critical code paths like authentication, token validation, and database queries, Supermaven's completions can introduce subtle vulnerabilities — such as completing a SQL query without parameterization or missing a signature verification step.

mediumCode Quality

Existing codebase anti-patterns replicated across new files at high velocity

Supermaven learns from your codebase, which means bad patterns — deprecated APIs, insecure functions, or architectural mistakes — get propagated to new code rapidly due to how quickly completions are accepted.

mediumTesting

Test completions mirror happy-path structure without edge case coverage

When completing test code, Supermaven tends to replicate the structure of surrounding tests, which often means test completions also omit edge cases, error paths, and boundary conditions that the surrounding tests miss.

mediumPerformance

Performance-inefficient completions that compile and run but do not scale

Supermaven completes code that is correct but not optimal — for example, completing a nested loop where a map lookup would work, or adding an N+1 query pattern in a data-fetching function that will perform poorly under load.

mediumPerformance

Import completions that add large unused dependencies to the bundle

Supermaven may complete import statements that add entire libraries when only a single utility function is needed, contributing to bundle bloat that affects load performance in frontend applications.

lowDeployment

Deployment configuration files completed with development-mode settings

When completing Dockerfile, CI workflow, or server config files, Supermaven may fill in development-appropriate values — like DEBUG=true or missing health check configurations — that are incorrect for production deployment.

mediumCode Quality

Inconsistent error handling style across functions completed in the same file

Supermaven completes error handling based on the nearest local context, which can result in a mix of thrown exceptions, returned error objects, and ignored errors within the same module.

Frequently asked questions

How does Supermaven's 1M token context window actually improve completions?

The large context window means Supermaven can include more of your codebase when generating completions — more file context, more type definitions, more usage examples. In practice, this means completions are more likely to use your existing utilities and match your established patterns compared to tools with smaller context windows.

Is Supermaven faster than GitHub Copilot and does the speed difference matter?

Supermaven is measurably faster than Copilot in most benchmarks, with completions appearing before you finish typing rather than after a pause. Whether this matters depends on your workflow — some developers find the speed addictive, while others find that Copilot's slight delay gives them time to consider whether to accept the suggestion.

Does Supermaven work in all IDEs or only VS Code?

Supermaven supports VS Code, JetBrains IDEs, and Neovim via an LSP plugin. The experience is most polished in VS Code, but JetBrains support is functional for IntelliJ, WebStorm, and PyCharm. Check their website for the latest IDE compatibility list as support expands.

How should we review Supermaven completions to avoid introducing bugs?

The biggest risk with fast completion tools is the speed of acceptance. Establish a team norm of pausing on multi-line completions to verify function signatures, type correctness, and security-sensitive paths before accepting. Running TypeScript's type checker and linting on save catches many issues that slip through rapid acceptance.

Does Supermaven train on our private code?

Supermaven's free plan uses code for model improvement. The Pro and Enterprise plans include options to opt out of training data collection. If your codebase contains proprietary business logic or sensitive information, review their privacy policy and use an Enterprise plan with data isolation guarantees.
