Pi Agent vs OpenCode after 100+ Hours of Real Use ✌️
Open-source coding agents had a weird start to 2026. In January, Anthropic suddenly blocked third-party tools from using Claude subscriptions. Overnight, with no warning. OpenCode got hit the hardest. The team had to remove Claude login support after legal pressure. The commit message was literally just: “anthropic legal requests.” PI never really cared. It was never built around one provider…
Pi Agent and OpenCode are two popular open-source coding agents that have been tested for real-world usage. Pi Agent, developed by Mario Zechner, is a minimal terminal coding agent that provides four tools and expects the user to build the rest themselves. OpenCode, on the other hand, is the most starred open-source coding agent with over 199k stars, offering a full Claude Code experience without locking the user to a single provider.
In the evaluation, Pi Agent achieved a 21/30 task success rate, with a median task completion time of 362.9 seconds. OpenCode, meanwhile, successfully completed 19/30 tasks, with a median task completion time of 280.6 seconds. Both agents have their strengths and weaknesses, but overall, Pi Agent edges out OpenCode in terms of efficiency, hackability, and raw results.
However, OpenCode has a wider range of features, provider support, and a simpler onboarding process. Ultimately, the choice between Pi and OpenCode depends on the user's preferences and coding style.
