GenAI Release Gate - Test your LLM applications before release.

Why?

LLM applications are non-deterministic. The same prompt can produce different outputs, leak PII, or be vulnerable to prompt injection. ReleaseGate catches these issues before production.

Your Code → LLM → ReleaseGate → ✅ Deploy or 🚫 Block

Quick Start

# Install
npm install -g @evidentai/cli

# Set your API key
export OPENAI_API_KEY=sk-...

# Create config
releasegate init

# Run tests
releasegate run

Commands

releasegate run

Run test suites against your LLM.

releasegate run                     # Run all tests
releasegate run -c config.yaml      # Specific config file
releasegate run --suite safety      # Run one suite only
releasegate run --dry-run           # Preview without running
releasegate run --verbose           # Detailed output
releasegate run --format junit -o results.xml  # JUnit output

Options: | Flag | Description | |------|-------------| | -c, --config <path> | Config file (default: releasegate.yaml) | | -s, --suite <name> | Run specific suite(s) only | | --concurrency <n> | Parallel test limit (default: 5) | | --timeout <ms> | Timeout per test in milliseconds (default: 60000) | | --retries <n> | Max retries per LLM call (default: 3) | | --retry-delay <ms> | Base retry delay in milliseconds (default: 1000) | | -o, --output <path> | Output file path | | --format <type> | json, tap, junit, pretty | | --upload | Upload results to ReleaseGate cloud | | --no-thresholds | Skip threshold checks (always exit 0) | | --dry-run | Show tests without executing | | -v, --verbose | Verbose output | | -q, --quiet | Suppress all output except errors |

Reliability & Rate Limits

ReleaseGate retries transient API failures (timeouts, 429s, and 5xx errors) with exponential backoff and jitter. If the provider returns Retry-After or rate-limit reset headers, those delays are respected. Tune behavior with --retries and --retry-delay.

releasegate init

Create a starter config file.

releasegate init                    # Creates releasegate.yaml
releasegate init -o custom.yaml     # Custom filename
releasegate init --force            # Overwrite existing

releasegate validate

Validate config without running tests.

releasegate validate
releasegate validate -c custom.yaml

Evaluators

exact-match

Strict string comparison.

evaluator: exact-match
expected: "Hello, World!"
config:
  case_sensitive: false  # default: true
  trim: true             # default: true

contains

Check for required keywords.

evaluator: contains
expected: ["term1", "term2", "term3"]
config:
  match_all: true       # true = AND, false = OR (default)
  case_sensitive: false # default: false

llm-judge

LLM-as-judge with custom criteria (G-Eval approach).

evaluator: llm-judge
criteria: |
  Evaluate the response for:
  - Accuracy of information
  - Clarity of explanation
  - Professional tone
config:
  score_range: [1, 5]   # Scoring range
  pass_threshold: 4     # Minimum to pass

pii

Detect personally identifiable information.

evaluator: pii
config:
  fail_on:
    - email
    - phone
    - ssn
    - credit_card
    - ip_address

Detected PII types: email, phone, ssn, credit_card, ip_address, address, name, date_of_birth

prompt-injection

Multi-layer prompt injection detection.

evaluator: prompt-injection
config:
  sensitivity: high     # low, medium, high
  detection_methods:
    - heuristic         # Pattern matching
    - canary            # Canary token detection

Detects: ignore instructions, system prompt leaks, jailbreaks (DAN), role switching, encoded attacks

custom

Your own evaluation logic.

evaluator: custom
config:
  script: ./my-evaluator.js

// my-evaluator.js
module.exports = async function({ input, output, config }) {
  const passed = output.length < 500;
  return {
    passed,
    score: passed ? 1.0 : 0.0,
    reason: passed ? "Response is concise" : "Response too long"
  };
};
