Gate by Constellation
Gate sits between agents and model providers to log requests, compress context and optionally screen content. Its Connect desktop app advertises routing existing coding tools, while the gateway supports provider keys or prepaid model usage.
Best for: Relevant to developers comparing gateway costs and screening on representative safe test requests.
- 02
RunInfra
RunInfra provides hosted open models through OpenAI- and Anthropic-compatible APIs. It offers prepaid token billing and workspace coding plans, with session-aware caching and separately reported cached-token usage.
Best for: Relevant to developers measuring open-model compatibility and real billed usage for their own workloads.
- 03
Pre.dev
pre.dev is a long-horizon coding agent that plans, builds, and verifies software over extended runs in the browser or terminal. It connects to many SaaS tools, publishes previews, and sells separate RL coding tasks to AI labs through pre.dev Labs.
Best for: Developers and teams who want an autonomous coding agent with planning, verification, integrations, and optional enterprise RL task sourcing.
- 04
Edgee
Edgee routes coding-agent requests through configurable model policies, compression and usage reporting. It advertises provider fallback and cost attribution by developer, repository and pull request, with team controls on paid plans.
Best for: Relevant to engineering teams reconciling request costs and testing budget-triggered routing.
- 05
Mainbrella
Mainbrella provides API-managed Linux workspaces for AI agents to execute commands, transfer files and open web previews. Applications can select runtime images, inspect stdout and exit codes, or connect by SSH and a browser terminal. Fixed monthly plans cap compute and sessions, while saved-workspace features preserve selected filesystem state.
Best for: Developers integrating command execution and temporary isolated filesystems into coding agents or tool-calling applications.
- 06
Token Harbor
Token Harbor exposes several model providers through one OpenAI-compatible API with free routes and paid usage passes. Users choose model IDs, review usage allowances and decide whether calls pause or continue from a paid balance at the pass limit.
Best for: Relevant to developers comparing model routes while controlling allowance exhaustion and data handling.
- 07
Trigger.dev
Trigger.dev runs TypeScript tasks and durable AI agents with retries, queues, streaming and observability. Its chat-agent workflow supports paused tool approvals and continued execution, while deployments version task code and Realtime exposes run status.
Best for: Relevant to developers managing long-running agent steps with reviewed tool actions and visible run history.
- 08
Bitrise Build Hub
Bitrise Build Hub runs existing GitHub Actions workflows on managed macOS and Linux infrastructure. It gives teams and coding-agent workflows mobile build capacity without maintaining their own runners.
Best for: For mobile teams keeping GitHub Actions while moving build execution onto managed Apple-silicon and Linux runners.
- 09
MeshPilot
MeshPilot’s MeshConsole organizes coding agents in persistent terminals and chat panes over local folders. Studio adds linked agent windows, a task board and project memory; MeshUtility is a separate dictation and prompt-rewriting tray tool.
Best for: Relevant to developers managing agent sessions while reviewing folder permissions, task handoffs and changes.
- 10
CopilotKit
CopilotKit connects agents to product interfaces through AG-UI, chat and generative UI components, frontend actions and shared state. Developers can use ready-made components or headless APIs, with hosting and enterprise deployment options.
Best for: Relevant to developers embedding interactive agent workflows into existing products.
