Use Case Recommendations
Best for: INK
INK is a hosting platform designed on the assumption that the thing deploying your code may not be a person. It positions itself as cloud infrastructure for agent-built apps: no Dockerfiles, no CI pipelines, no infrastructure config. You push to INK's own git remote or connect a GitHub repo, or you let a coding agent push through the CLI, an agent Skill, or MCP, and INK detects the stack — Next, Rails, FastAPI, Go — builds it, and serves it on a URL with automatic TLS on a custom domain. Postgres and Redis templates and persistent volumes sit alongside app services, so stateful workloads live in the same canvas rather than a separate console. Billing is per-minute while a service runs, which matters for the agent case where a dozen short-lived preview environments are normal. The part that distinguishes INK from a generic PaaS is that every observability surface is dual-addressed: a human dashboard with filterable logs and real-time metric charts, and the identical signals reachable programmatically through the CLI, Skills and MCP, so an agent can read its own error logs and iterate without a human relaying them. Agents can also query their remaining credit balance over MCP, which is the vendor's answer to runaway autonomous spend. The published integration list covers Claude Code, Cursor, Codex, Gemini CLI, Windsurf, VS Code, Kimi Code, Open Code, Antigravity and Goose.
Ideal use cases:
- •Teams or individuals who need git-push or agent-push deploys with automatic stack detection
- •Teams or individuals who need postgres and redis templates plus persistent volumes beside app services
- •Teams or individuals who need per-minute billing only while a service is running
- •Teams or individuals who need cli, agent skills and mcp access to deploys, logs and metrics
- •Anyone focused on deployment workflows
- •Anyone focused on paas workflows
Best for: PromptShuttle
PromptShuttle is a drop-in OpenAI-compatible endpoint that runs multi-agent orchestration server-side, so the calling application never contains agent logic. You send an ordinary chat-completions request naming a flow — "research-agent" — and behind that single call the proxy spawns sub-agents, routes each to whichever provider suits it, executes tool calls and returns one finished answer. The company draws the contrast with SDK-based frameworks explicitly: with an SDK, agent logic lives in your code, changing an agent means redeploying your application, and every team builds its own plumbing for providers, retries and cost tracking; here the logic lives in the proxy, changing an agent is a config update, and one deployment serves every team. That shape suits the cases it markets to — platform teams offering AI to internal teams without each one learning a framework, legacy software made agent-capable through webhooks with no rewrite, agencies running isolated multi-tenant configurations per client, and background job runners like Trigger.dev or Temporal calling AI as a service. The dashboard shows the full execution graph per request with sub-agent spawns, tool calls, timing and per-step cost, plus flow analytics and per-tenant budgets. It also exposes its own MCP server at a single URL, so a coding assistant can create flows, edit prompts and query analytics conversationally.
Ideal use cases:
- •Teams or individuals who need standard chat-completions endpoint, no sdk required
- •Teams or individuals who need server-side sub-agent spawning and tool execution
- •Teams or individuals who need agent changes are config updates, not redeploys
- •Teams or individuals who need multi-provider routing per agent
- •Anyone focused on orchestration workflows
- •Anyone focused on openai-compatible workflows
