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.
- 02
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.
- 03
Actx0
Actx0 stores agent sessions and extracts compact memories for semantic retrieval before the next model reply. Managed workspaces include knowledge search, memory consolidation, keys, audit events and usage tracking.
Best for: Relevant to developers retrieving bounded context instead of replaying full chat transcripts.
- 04
ZooWork
ZooWork builds, deploys and manages agents using business knowledge, tools and scheduled workflows. It offers a workspace-based Agent Builder, a separately scoped managed-agent API and enterprise deployment services.
Best for: Relevant to domain experts delivering agents with shared knowledge and managed runtime.
- 05
Velane
Velane deploys agents, APIs and small apps through versioned Bun/Python workflows, isolated invocation sandboxes and development, staging and production environments. MCP operations cover connected accounts, execution logs and promotion to HTTP endpoints.
Best for: Relevant to builders who want agent-managed deployment with visible environments and rollback.
- 06
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.
- 07
Heroku
Heroku is Salesforce’s cloud application platform for deploying, scaling, and operating web apps and workers without running your own servers. Teams use Git- and container-based deploys, managed data services, add-ons, and enterprise controls while Heroku handles runtime infrastructure.
Best for: Development teams shipping and operating web apps, APIs, and background workers who want a managed PaaS instead of raw VMs.
- 08
Letta
Letta is an AI research lab and product company building stateful agents whose memory and capabilities evolve over time, originating from MemGPT research. It ships Letta Agent software, a CLI, and cloud plans for individuals, teams, and API developers.
Best for: Engineers and teams building long-horizon coding or workflow agents that need durable memory and sandboxed execution.
- 09
Freestyle
Freestyle provides full Linux VMs purpose-built for long-running AI agents with millisecond startup, live cloning, pause/resume, nested Docker, and custom networking. Developers use the VMs for coding agents, browser automation, and containerized workloads.
Best for: Teams building autonomous agents that need persistent Linux environments, previews, and Docker inside the VM.
- 10
Aramb
Aramb combines model routing, voice, browser execution, sandboxes, memory, tool integrations and usage billing for AI-agent products. It supports no-code authoring and developer integration within a shared credit system.
Best for: Relevant to builders combining agent execution and usage-based billing without separately wiring each runtime service.
