Docker Agentic Platform alternatives

Docker Agentic Platform is listed under Agents: Runs your agents in isolated sandboxes on Docker-managed cloud infrastructure. Experimental. We compare it with 15 other Agents tools that have researched data. 15 of them offer a free plan or are free to use (6 open source), and 0 are paid only. Docker Agentic Platform itself is paid.

Order: Sorted by how much you can use for free (free or open source first, then free plan with paid tiers, then paid only), then by the number of documented features, then alphabetically. No ratings or reviews are used.

Tool	Pricing	Free tier	Key features	Who it's for
Docker Agentic Platform this tool	Paid First $25 of compute included; then per-second rates	No	Predefined sandboxes for Claude Code, Codex, Gemini CLI, Copilot, and OpenCode Stores model API keys as secrets, never inside the sandbox Network policies decide what each sandbox can reach	—
Omnara	Freemium (free plan + paid tiers) Platform fee $0; pay as you go for models and machines	Yes	Runs agents through one REST API, a TypeScript SDK, and a CLI Uses OpenAI, Anthropic, OpenRouter, LiteLLM, or a model you host Runs agents on sandboxes or on your own macOS or Linux machine	Teams who want to run production agents on their own models and machines.
OpenShell	Free and open source	Yes	Runs each agent in an isolated sandbox Confines files and system calls with kernel controls inside the sandbox Checks every network connection against policy before it leaves the sandbox	Teams that run fleets of autonomous agents and want policy on files, network, and credentials.
Composio	Freemium (free plan + paid tiers)	Yes	Gives agents access to more than 1,500 apps Loads only the catalog actions a task needs Manages OAuth sign-in and per-account scopes	Developers and teams connecting AI agents and assistants to work apps.
E2B	Freemium (free plan + paid tiers) Paid plans from $150/month	Yes	One Linux microVM per agent session with shell and browser Run sandboxes on E2B cloud or AWS, GCP, or Azure Run Python or JavaScript and return charts, tables, and images	Teams that build and run AI agents.
Agensh	Free and open source	Yes	Agents discover and claim sub-tasks, share findings, verify results, and merge progress Runs without a central orchestrator, using a shared workspace, messages, and shared context Published experiments scale the harness to 1,024 agents	Engineers reproducing a self-organized multi-agent harness on one machine.
LearnHarness	Free and open source	Yes	Measures where understanding ends, then plans a dependency map from there to the goal Teaches one reasoning step at a time, then runs separate practice sessions Stores propositions and reasoning chains in a knowledge graph across sessions	People who want an agent to teach a subject from what they already understand.
ESP32 iPhone Agent	Free and open source	Yes	Mirrors the iPhone screen over AirPlay into JPEG frames Controls the phone with an ESP32-S3 USB mouse and keyboard Uses any OpenAI-compatible vision model, cloud or local	People who want an AI model to operate a real iPhone.
Haystack	Free and open source	Yes	Wire retrieval, reasoning, memory, and tools into agent flows Plug in OpenAI, Anthropic, Mistral, Hugging Face, and vector databases Run serializable pipelines on Kubernetes with logging and monitoring	Teams and developers building LLM-powered agents and NLP applications.
LangChain	Freemium (free plan + paid tiers)	Yes	Trace agent runs step by step and search traces fast Turn traces into datasets and score each agent step Deploy agents with persistent state and isolated code sandboxes	For individual developers and teams of any size building agents.
Modal	Freemium (free plan + paid tiers) Paid plans from $250/month	Yes	Serve language, image, video, and audio models live or in batch Run isolated sandboxes for coding agents and untrusted code Fine-tune models and run reinforcement learning on GPUs	For teams that develop, train, and serve AI applications at scale.
Harness²	Free and open source	Yes	Task-level recursion proposes edits, probes them on the same task, and composes a harness Harnessing-level recursion keeps adopted harnesses and lessons for the next task Eight editable parts: system prompt, guardrails, memory, tool guidance, subagents, skills, scripts, and plugins	Engineers refining an agent harness for tasks unseen when that harness was designed.
Alter	Freemium (free plan + paid tiers) Free: 10,000 calls/mo; Starter $50/mo	Yes	Stores credentials in a vault and injects them per request Checks each call against a default-deny policy Gives each agent its own identity and scopes	Teams that need to control what AI agents can do with user credentials.
Agno	Freemium (free plan + paid tiers) Paid plans from $150/month	Yes	Build agents, teams, and workflows using 100+ toolkits Expose agents as a product API or MCP server Run the platform in any cloud, on-prem, or locally	Engineers and teams who build customer-facing and internal agents in their own cloud.
Browser Use	Freemium (free plan + paid tiers) Credits from $5	Yes	Remote browsers for agents via SDK, REST, or CDP Hosted agents that complete browser tasks MIT-licensed code you can run on your machine	For AI startups and automation teams that run browser agents.
Browserbase	Freemium (free plan + paid tiers) Paid plans from $20/month	Yes	Cloud browsers agents can drive to use websites Search for sites from a single query Fetch any URL as HTML, JSON, or markdown	Developers and companies building agents that browse and act on the web.
