Should you build your own AdaL?
Coding agent that routes work to specialized workers across frontier model families
⌨️ featured in the best vibe coding tools
The core loop is genuinely reachable: open-source agents already route across model families, run tools, and edit repos, and a weekend of wiring gets you a personal version. What does not fall out of a weekend is the harness around the model, which is where AdaL claims its numbers come from, plus browser-based verification, clustered code review, and the team controls. You end up with an agent that works and a noticeably worse recovery rate on long tasks.

Build me a multi-model coding agent CLI to replace AdaL, in an empty folder.
Stack: Python 3.12, one file per module, no framework.
- Providers: Anthropic, OpenAI and Google, behind a single `chat(model, messages, tools)`
function. Keys from .env via python-dotenv, never hardcoded. A `--model` flag
switches families mid-session without restarting.
- Tools the agent can call: read_file, write_file, list_dir, run_shell, run_tests.
run_shell prints the command and waits for y/n unless I pass --yolo.
- An orchestrator loop: a planner call splits my request into numbered steps, then
each step runs as a fresh sub-agent with its own context window and only the tools
it needs. Sub-agent results append to a shared markdown scratchpad on disk.
- Persist every session as JSONL under .agent/sessions/ so I can replay or resume.
A `--resume <id>` flag reloads the scratchpad and continues.
- After any step that edits files, automatically run the test command from
pyproject.toml and feed failures back to the same sub-agent for one retry.
- Print a running token and dollar total per provider at the end of every turn.
- Out of scope, deliberately: browser automation, a GUI, team accounts, and any
hosted service. Those are the parts the subscription is actually selling.
- README: setup, the .env template, how to add a fourth provider, and one honest
paragraph on where this loses to a tuned commercial harness on long tasks.The prompt opens pre-filled in your agent. Review it before running.
What would building your own look like?
Wire a terminal agent to several provider APIs, give it file, shell and test tools, and let a planner sub-agent hand tasks to specialized workers in one session.
What you will need
- Node 20 or Python 3.12
- API keys for at least two providers in .env
- Git repo to work against
- Playwright if you want the browser-verification worker
Because the gap between an agent that runs and an agent that finishes is mostly unglamorous harness work, and nobody wants to maintain it on a weekend. The flat subscription across every frontier model is the other half: DIY means holding API accounts with six vendors and watching the meter on every long run.

Free tierno free tier, only a 7-day trial
Billing termsmonthly + annual for self-serve plans, annual advertised at 17% off; Teams and Enterprise are custom-quoted
Additional costsModel inference is included in the subscription rather than billed per token, so the usage multipliers between Pro, Max and Max+ are the real cost lever and are not expressed in published numeric limits.

Is it cheaper to build or buy AdaL?
Adjust the numbers: hours to build, your hourly rate, running costs and the subscription price.
Over 24 months, subscribing is cheaper.
Starting hours estimated from the analysis (weekend). Does not price what you give up (support, integrations, security).
Is AdaL free?
There is no permanently free plan; new accounts get 7 days of free access and then have to pick a paid tier. The paid plan is Pro at $20/mo (checked 10/20/2026).
Can I rebuild AdaL?
Kinda. The core of AdaL is buildable in a weekend with the prompt on this page, but there are real gaps: harness tuning: the planning, recovery and verification work that separates a demo agent from one that finishes long tasks, browser-use verification of the app you just changed. Read the honest list above before committing.
How much does AdaL cost?
AdaL costs about $20/mo (Pro, checked 10/20/2026), which is $199 per year.
What do I lose by replacing AdaL?
Honestly: harness tuning: the planning, recovery and verification work that separates a demo agent from one that finishes long tasks; browser-use verification of the app you just changed; review clustering that groups a large diff into risk-ranked units; one bill across every frontier provider instead of six metered API accounts; SSO, SAML/SCIM, zero data retention and org-level model deny lists. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to AdaL?
Yes: OpenCode (A terminal coding agent with no loyalty to any model vendor; you still pay the meter.) Cline (An agent that lives in the editor you already use; the model bill is still yours.) Goose (A desktop and terminal agent with real extension support, and no pretence that the model is free.) All 3 curated free alternatives are at https://viberadar.si/adal/alternatives.
