Fine-tune and customize Small Language Models using your organization's proprietary data and domain-specific requirements. Adapt pre-built SLMs to your specific use cases and terminology.
Deploy SLMs in on-premise or private cloud environments for complete data control and compliance. Avoid sending sensitive data to third-party cloud APIs while maintaining full operational control.
Monitor SLM inference performance, accuracy metrics, and cost efficiency in production. Identify optimization opportunities and track model performance over time.
Transforms Vitest's native test execution output into a machine-readable JSON or text format optimized for LLM parsing, eliminating verbose formatting and ANSI color codes that confuse language models. The reporter intercepts Vitest's test lifecycle hooks (onTestEnd, onFinish) and serializes results with consistent field ordering, normalized error messages, and hierarchical test suite structure to enable reliable downstream LLM analysis without preprocessing.
Unique: Purpose-built reporter that strips formatting noise and normalizes test output specifically for LLM token efficiency and parsing reliability, rather than human readability — uses compact field names, removes color codes, and orders fields predictably for consistent LLM tokenization
vs alternatives: Unlike default Vitest reporters (verbose, ANSI-formatted) or generic JSON reporters, this reporter optimizes output structure and verbosity specifically for LLM consumption, reducing context window usage and improving parse accuracy in AI agents
Organizes test results into a nested tree structure that mirrors the test file hierarchy and describe-block nesting, enabling LLMs to understand test organization and scope relationships. The reporter builds this hierarchy by tracking describe-block entry/exit events and associating individual test results with their parent suite context, preserving semantic relationships that flat test lists would lose.
Unique: Preserves and exposes Vitest's describe-block hierarchy in output structure rather than flattening results, allowing LLMs to reason about test scope, shared setup, and feature-level organization without post-processing
vs alternatives: Standard test reporters either flatten results (losing hierarchy) or format hierarchy for human reading (verbose); this reporter exposes hierarchy as queryable JSON structure optimized for LLM traversal and scope-aware analysis
Malted AI scores higher at 32/100 vs vitest-llm-reporter at 29/100. Malted AI leads on adoption and quality, while vitest-llm-reporter is stronger on ecosystem. However, vitest-llm-reporter offers a free tier which may be better for getting started.

Parses and normalizes test failure stack traces into a structured format that removes framework noise, extracts file paths and line numbers, and presents error messages in a form LLMs can reliably parse. The reporter processes raw error objects from Vitest, strips internal framework frames, identifies the first user-code frame, and formats the stack in a consistent structure with separated message, file, line, and code context fields.
Unique: Specifically targets Vitest's error format and strips framework-internal frames to expose user-code errors, rather than generic stack trace parsing that would preserve irrelevant framework context
vs alternatives: Unlike raw Vitest error output (verbose, framework-heavy) or generic JSON reporters (unstructured errors), this reporter extracts and normalizes error data into a format LLMs can reliably parse for automated diagnosis
Captures and aggregates test execution timing data (per-test duration, suite duration, total runtime) and formats it for LLM analysis of performance patterns. The reporter hooks into Vitest's timing events, calculates duration deltas, and includes timing data in the output structure, enabling LLMs to identify slow tests, performance regressions, or timing-related flakiness.
Unique: Integrates timing data directly into LLM-optimized output structure rather than as a separate metrics report, enabling LLMs to correlate test failures with performance characteristics in a single analysis pass
vs alternatives: Standard reporters show timing for human review; this reporter structures timing data for LLM consumption, enabling automated performance analysis and optimization suggestions
Provides configuration options to customize the reporter's output format (JSON, text, custom), verbosity level (minimal, standard, verbose), and field inclusion, allowing users to optimize output for specific LLM contexts or token budgets. The reporter uses a configuration object to control which fields are included, how deeply nested structures are serialized, and whether to include optional metadata like file paths or error context.
Unique: Exposes granular configuration for LLM-specific output optimization (token count, format, verbosity) rather than fixed output format, enabling users to tune reporter behavior for different LLM contexts
vs alternatives: Unlike fixed-format reporters, this reporter allows customization of output structure and verbosity, enabling optimization for specific LLM models or token budgets without forking the reporter
Categorizes test results into discrete status classes (passed, failed, skipped, todo) and enables filtering or highlighting of specific status categories in output. The reporter maps Vitest's test state to standardized status values and optionally filters output to include only relevant statuses, reducing noise for LLM analysis of specific failure types.
Unique: Provides status-based filtering at the reporter level rather than requiring post-processing, enabling LLMs to receive pre-filtered results focused on specific failure types
vs alternatives: Standard reporters show all test results; this reporter enables filtering by status to reduce noise and focus LLM analysis on relevant failures without post-processing
Extracts and normalizes file paths and source locations for each test, enabling LLMs to reference exact test file locations and line numbers. The reporter captures file paths from Vitest's test metadata, normalizes paths (absolute to relative), and includes line number information for each test, allowing LLMs to generate file-specific fix suggestions or navigate to test definitions.
Unique: Normalizes and exposes file paths and line numbers in a structured format optimized for LLM reference and code generation, rather than as human-readable file references
vs alternatives: Unlike reporters that include file paths as text, this reporter structures location data for LLM consumption, enabling precise code generation and automated remediation
Parses and extracts assertion messages from failed tests, normalizing them into a structured format that LLMs can reliably interpret. The reporter processes assertion error messages, separates expected vs actual values, and formats them consistently to enable LLMs to understand assertion failures without parsing verbose assertion library output.
Unique: Specifically parses Vitest assertion messages to extract expected/actual values and normalize them for LLM consumption, rather than passing raw assertion output
vs alternatives: Unlike raw error messages (verbose, library-specific) or generic error parsing (loses assertion semantics), this reporter extracts assertion-specific data for LLM-driven fix generation
