OpenCode vs AmpCode: IDE daily driver or terminal agent?

OpenCode and AmpCode get compared in feature lists that ignore how teams actually work. This page is a decision memo: what each is for, what only one of them does well, and which should be your default.

OpenCode is a Terminal agent aimed at Provider-neutral terminal use (Free (BYO keys)). AmpCode is a Terminal + IDE agent aimed at Unconstrained agentic coding with multi-model routing (Pay-as-you-go (free tier ~$10/day)).

Quick verdict

Default for most teams reading this angle: OpenCode — local-first execution. Keep AmpCode as a specialist when its unique strengths matter.

Feature matrix

IDE daily driver vs terminal agent

OpenCode is positioned as Terminal agent. AmpCode is Terminal + IDE agent.

IDE-shaped tools win for tight edit loops (see the diff, jump files). Terminal agents win for long jobs you can detach (migrations, CI babysitting). Many teams should run both lanes, not pick a religion.

Default: put interactive day-to-day work in the IDE-shaped tool, and long-horizon automation in the terminal agent—if both can do either, pick by where your team already stares six hours a day.

Strengths (from product positioning)

OpenCode

Pros: Multi-provider support; Free and open source; Skill-driven execution; Copilot provider integration.

Cons: Archived / no active development; No vision support; No subagents.

AmpCode

Pros: Multi-model routing; Unconstrained token usage; Free daily credits; Team thread sharing; Code review built-in.

Cons: Pay-as-you-go costs unpredictable; Free tier closed to new signups; No flat subscription option; VS Code extension deprecated.

Public adoption signals

Numbers below come from terminalblog’s adoption snapshots (npm/PyPI/GitHub when available). They change; treat them as relative, not marketing.

Full board: leaderboard.

Install / source paths

OpenCode

• Package: @opencode-ai/sdk (npm) — try npx -y @opencode-ai/sdk or install per upstream docs
• Source: opencode-ai/opencode

AmpCode

• Check the project site / GitHub for current install steps (CLI packages change often).

Always confirm install commands on the upstream repo—package names move.

When to choose which

Choose OpenCode when

• Your main job is Open-source alternative with flexible provider choice
• You need local-first execution (which AmpCode lacks in our matrix)
• You can live with: Archived / no active development; No vision support

Choose AmpCode when

• Your main job is Maximum capability, variable billing
• You need subagents / agent teams (which OpenCode lacks in our matrix)
• You can live with: Pay-as-you-go costs unpredictable; Free tier closed to new signups

Use both when

• Interactive coding and long unattended jobs are different lanes on your team
• You are migrating and need a temporary dual stack
• Compliance needs a local-first path even if daily work is commercial

Three jobs to run before you standardize

1. Parallel tickets: fan out lint/docs/tests. Prefer AmpCode with separate worktrees. Keep OpenCode for a single deep refactor.
2. Daily edits: stay in AmpCode. Long migrate / CI loop: hand off to OpenCode if it is the stronger terminal agent.

Record: default tool, specialist tool, and forbidden actions (e.g. no prod deploys without a human). Put that in AGENTS.md.

FAQ

Can I run OpenCode and AmpCode side by side?

Yes. Use separate worktrees or clones so they never write the same files concurrently.

Which is cheaper?

Both pricing lines are above. Model your spike week (tokens × retries × seats). See the pricing guide.

Does SWE-bench decide this?

OpenCode lists 88.0%. AmpCode has no solid public SWE-bench in our dataset. Benchmarks under-predict IDE feel, Windows reliability, and cron ops.

Bottom line

Start with OpenCode for this decision (local-first execution). Keep AmpCode when you need its unique strengths: subagents / agent teams. Revisit when pricing, models, or your job mix changes.

Comparing agents is half the work. aiFiesta can simplify multi-model access while you test workflows.

Operator notes that usually get skipped

Permissions: Agents with shell access can delete work as easily as they write them. Prefer clear approval prompts and deny-by-default for network and production credentials. OpenCode and AmpCode both need an explicit policy for force-push, .env reads, and cloud deploys.

Windows vs macOS: Path separators, PowerShell vs bash, and orphaned child processes still decide winners more often than marketing benchmarks. Run the same three jobs on the OS your team ships on before you standardize on OpenCode or AmpCode.

Lockfiles: Never run two agents against the same package-lock / pnpm-lock / Cargo.lock concurrently. That failure mode looks like “the agent is dumb” when it is really shared mutable state. Give OpenCode and AmpCode separate worktrees.

Memory vs amnesia: OpenCode is positioned for Provider-neutral terminal use; AmpCode for Unconstrained agentic coding with multi-model routing. Long-running memory or knowledge features only pay off if you invest in what they store; otherwise you pay complexity for zero retention.

Escape hatch: Can you export history, pin versions, and keep working if a model vendor deprecates a SKU next quarter? Multi-provider (Yes vs Yes) and open source (Yes vs No) matter more here than any single benchmark number.

Team rollout: Pick one default (OpenCode), one specialist, document forbidden actions, and revisit quarterly. Tooling churn is faster than most internal standards documents.
