Products, side by side

Algorithmic pairing — assembled from recorded fields, not hand-checked

Kilo Code

API service

Kilo GatewayAPI service

OpenAI-compatible inference API that routes requests to 500+ models from 60+ providers at provider rates, with bring-your-own-key support, per-request cost tracking and organization model and provider controls.

AI agent

Kilo Cloud AgentsAI agent

Runs the Kilo coding agent in an isolated cloud Linux container started from a browser or phone: it clones the repository, works on its own branch and commits and pushes after every message, and can be started by webhook or on a schedule.

Kilo CodeAI agent

AI coding agent for VS Code, JetBrains IDEs, CLI and cloud platforms, with modes for coding, architecture planning, debugging and code review, access to 500+ models and zero AI-inference markup (bring-your-own-key supported).

Security AgentAI agent

Turns GitHub Dependabot alerts into tracked findings, uses an AI triage model and a sandboxed analysis of the repository to decide whether each vulnerable dependency is actually reachable, opens remediation pull requests and tracks remediation deadlines with audit reports.

Developer tool

Kilo Code ReviewerDeveloper tool

Reviews pull requests on GitHub or GitLab (Bitbucket coming soon) and posts inline comments on bugs, security issues, performance and style, with a strictness setting and team instructions, and can also review uncommitted changes locally in VS Code or JetBrains.

Mastra

API service

Mastra GatewayAPI service

An OpenAI- and Anthropic-compatible model gateway that routes one API key to 300+ models with provider failover, and adds observational memory that compresses each conversation into notes so agents keep context without rebuilding it.

AI agent

Mastra CodeAI agent

An open-source terminal coding agent with Build, Plan and Fast modes and explore, plan and execute subagents, whose observational memory compresses the session into notes instead of compacting it, so long sessions keep their context.

Mastra FactoryAI agent

An open-source software delivery environment where coding agents take a connected repository's issues through investigation, planning, implementation and review to a reviewed pull request, with people deciding at each step; self-hosted or deployed on Mastra's platform.

Developer tool

MastraDeveloper tool

An open-source TypeScript framework that developers use to build, run and observe AI agents and workflows, with a hosted Studio and cloud deployment option.

Mastra StudioDeveloper tool

A shared workspace where a team inspects agent runs through traces and cost, latency and quality metrics, scores outputs with LLM-as-judge or code, runs dataset experiments and versions prompts and agent configurations, open to non-engineering reviewers without source access.

No counterpart

Mastra sells these in a stack layer with no product recorded for Kilo Code yet — nothing on the other side to compare them against.

Agent platform

Mastra Agent BuilderAgent platform

A UI mounted inside a team's own Mastra server for creating and operating internal agents, with multi-tenant workflows, role-based access and channel integrations, licensed for production under Mastra's enterprise licence.

Infrastructure service

Mastra Platform ObservabilityInfrastructure service

Hosted telemetry store for Mastra agents in production: it keeps the metrics, structured logs and step-by-step traces of model calls, tool calls and workflow steps for every run, with dashboards for cost, latency and quality scores.

Mastra ServerInfrastructure service

Hosted deployment target that runs a Mastra application's agents, tools and workflows as an API server from one command, with routing and scaling handled by Mastra and billing by CPU time and data egress.
