Show HN: A browser-based IDE with multi-agent terminal execution (no install) (opens in new tab)

2 pointsNickFORGE4mo ago5 comments

We built a browser-native IDE that runs a real Linux terminal and multi-agent coding tools directly in the browser — no installation or VM setup.

It supports: – A full CloudShell terminal (xterm.js + Node-PTY) – Multi-agent CLI execution (Aider, GPT Engineer, Claude Engineer) – Agents directly modifying files in the repo – UI plan generation + CLI build workflows – Zero local setup, zero dependencies

Demo: https://forge.synvara.ai

We would love technical feedback. Happy to answer questions about: – Browser terminal performance – WebSocket architecture – Agent orchestration – Security model

Thanks in advance — this community’s feedback is extremely valuable to us.

Thanks - glad it’s useful. The split screen came from our own frustration switching between a plan and the agent actually editing files. If anything feels off or confusing as you try it, I’m around and happy to adjust things.

Awesome, I'm going to check it out. The split screen is going to save a lot of time

"85–92% faster development "

well thanks for the hype, wtf is that based on?

Thanks for calling that out — fair question. The 85–92% number is from internal time-tracked tests comparing:

Before FORGE (baseline):

Spec/plan creation: 3–6 hours

Context switching (browser → IDE → terminal): ~1 hour

Manual copy/paste of generated code: 30–60 minutes

Manual setup + environment config: 30–90 minutes

After FORGE (CloudShell + agents):

Plan generation: 10–30 seconds

No local setup

Agents edit files directly in the repo

Terminal + UI in one interface

So the measurement isn’t “marketing hype” — it’s based on reducing a 6–12 hour workflow to 30–60 minutes on real feature builds.

Happy to share the breakdown or the feature sets we used if that helps.
