Routes requests to 500+ external LLM models (OpenAI, Anthropic, etc.) through a single API endpoint, abstracting provider-specific request/response formats and handling protocol translation. Implements request caching, automatic retries with exponential backoff, and fallback routing to alternative models when primary provider fails, reducing integration complexity from managing N provider SDKs to a single gateway interface.
Unique: Implements protocol-agnostic gateway that normalizes 500+ models into single API contract with built-in caching and retry logic, rather than requiring developers to manage provider-specific SDKs and error handling separately
vs alternatives: Faster integration than managing multiple provider SDKs directly because it abstracts protocol differences and adds automatic retries/caching at the gateway layer rather than application level
Stores, versions, and deploys prompts through a web IDE with git-like version control, enabling teams to track prompt changes, rollback to previous versions, and deploy new prompts to production through the gateway without code changes. Integrates with the unified gateway to serve deployed prompt versions at inference time, supporting A/B testing by routing traffic to different prompt versions.
Unique: Implements git-like prompt versioning with one-click deployment through the gateway, allowing non-technical users to manage prompt lifecycle without touching code or infrastructure
vs alternatives: Faster prompt iteration than hardcoding prompts in application code because changes deploy instantly without recompilation or redeployment of the main application
Enables A/B testing by deploying multiple prompt or model versions and routing traffic to each variant based on configurable split percentages (e.g., 50% to variant A, 50% to variant B). Automatically collects metrics for each variant (latency, cost, quality) and provides statistical comparison dashboards to determine which variant performs better. Supports gradual rollout (canary deployment) by starting with small traffic percentages and increasing based on performance.
Unique: Implements A/B testing with automatic metric collection and comparison dashboards, rather than requiring manual traffic splitting and external statistical analysis tools
vs alternatives: More integrated than manual A/B testing because traffic splitting and metric comparison are built-in, reducing the need for custom infrastructure and statistical analysis
Supports multiple team members with role-based access control (RBAC), enabling organizations to grant different permissions to engineers, product managers, and finance teams. Tracks who made changes to prompts, deployments, and alert configurations with audit logs, and supports team-scoped dashboards and alerts. Integrates with Google SSO for authentication (Pro/Team tiers) with SAML support on Enterprise tier.
Unique: Implements RBAC with audit logging and team-scoped resources, rather than all-or-nothing access, enabling organizations to grant granular permissions without sharing credentials
vs alternatives: More secure than shared credentials because RBAC enables fine-grained access control and audit trails provide accountability for changes to production configurations
Caches identical LLM requests at the gateway level and returns cached responses without calling the LLM provider, reducing latency and cost for repeated queries. Supports cache invalidation strategies (TTL, manual) and provides cache hit/miss metrics on dashboards. Works transparently for requests routed through the Respan gateway without application-level changes.
Unique: Implements transparent request-level caching at the gateway with cache metrics, rather than requiring application-level caching logic or external cache infrastructure
vs alternatives: More efficient than application-level caching because gateway-level caching works across all applications using the same Respan gateway, enabling cache hits across different services
Offers self-hosted deployment option for Enterprise tier customers, allowing Keywords AI infrastructure to run on customer's own servers or cloud account. Enables data residency compliance (e.g., data must stay in EU for GDPR). Self-hosted deployment includes all Keywords AI features (gateway, tracing, evaluation, dashboards). Requires customer to manage infrastructure, updates, and security patches. Specific deployment options (Kubernetes, Docker, VMs) not documented.
Unique: Offers self-hosted deployment option for Enterprise customers, enabling data residency compliance and reducing vendor lock-in. Allows organizations to run full Keywords AI stack on their own infrastructure.
vs alternatives: More compliant than cloud-only deployment for data residency requirements; more flexible than managed-only platforms because customers can choose deployment model.
Supports SAML 2.0 authentication for Enterprise tier customers, enabling integration with corporate identity providers (Okta, Azure AD, etc.). Allows centralized user management and access control through existing identity infrastructure. Supports role-based access control (RBAC) and single sign-on (SSO). SAML is available only on Enterprise tier; Pro/Team tiers use Google OAuth.
Unique: Implements SAML 2.0 authentication for Enterprise tier, enabling integration with corporate identity providers and centralized access control. Reduces friction for enterprise deployments by leveraging existing identity infrastructure.
vs alternatives: More secure than OAuth-only authentication because SAML enables centralized access control; more convenient for enterprises because it integrates with existing identity providers.
Captures complete execution traces from production LLM calls including request/response content, latency, token counts, cost, and custom metadata, storing traces in a searchable index with 7-30 day retention. Enables filtering and searching by content keywords, latency ranges, cost thresholds, quality tags, and custom properties, with trace replay functionality allowing developers to re-run requests through the playground for debugging.
Unique: Implements production trace capture with rich context (cost, latency, custom metadata) and replay-in-playground debugging, rather than simple logging that requires external tools to correlate and analyze
vs alternatives: More actionable than generic logging because traces include cost and latency metrics by default, and replay functionality eliminates the need to manually reconstruct requests for debugging
