Which Firebase Studio alternatives are still actively developed?

Visual Studio Code (newest commit 8 Oct 2026). Those dates are the newest commit on each project's default branch, read from the GitHub API on the date shown at the top of this page. We read the default branch rather than the repository's push timestamp, because a push to any branch moves the second one and makes a finished project look active.

Best Firebase Studio alternatives (2026)

Firebase Studio is an IDE that runs in the browser: Google's agentic cloud-based dev environment for full-stack AI apps. We name 14 alternatives below.

Quick answer

Of the 14 alternatives here, 3 have been researched claim by claim. Start with Google Antigravity.

Choose Google Antigravity when: Run Antigravity without leaving Visual Studio Code: Google's own extension puts agent chat, inline diff review and interactive plans into VS Code side panels, and installs a local `agy` backend service the first time you launch it. [antigravity.google/docs/ide]

It costs: Antigravity costs $0 a month for an individual, and the pricing page now labels that tier Generally Available rather than a preview. [antigravity.google/pricing]

How this list is ordered. Tools whose claims we have read and quoted come first, then tools whose repository we track, then catalogue entries we have not researched. Within each band the order is category and workflow overlap. A tool that has stopped is never the first answer. We publish no score out of five: every claim here traces to a source, and a number we could not justify would undermine the ones that can.

3 researched alternatives to Firebase Studio

Google Antigravity

antigravity.google

What it is: Google Antigravity is a platform rather than an editor: its IDE extensions put the same agent — side-panel chat, inline diff review and interactive plans — inside the editor you already use, so adopting Antigravity does not require adopting its IDE. [antigravity.google/docs/ide]

Where it hurts: You cannot point Antigravity at a model key you already hold: the plans page states there is no bring-your-own-key or bring-your-own-endpoint path, so the quota Google grants you is your only supply. [antigravity.google/docs/plans]

Price: Antigravity costs $0 a month for an individual, and the pricing page now labels that tier Generally Available rather than a preview. [antigravity.google/pricing]

Antigravity changes week to week and Google reserves the right to move the limits: 2.11.0 shipped on 2026-08-26 and the IDE extensions on 2026-08-20, so read every quota statement here as read on 2026-08-27.

Visual Studio Code

code.visualstudio.com

What it is: Visual Studio Code is the host, not the agent: one Session Target control switches a session between five harnesses — Local, GitHub Copilot, Anthropic Claude, OpenAI Codex and Cloud — so the editor stays fixed while the agent behind it changes. [code.visualstudio.com/docs/agents]

Choose Visual Studio Code when: Run Anthropic's agent without installing a second product: the Claude harness is enabled by default and bills either through a GitHub Copilot subscription or through your own Anthropic key. [code.visualstudio.com/docs/agents]

Where it hurts: The app you download is not the MIT repository: Microsoft ships Visual Studio Code as a licensed distribution of the open-source Code - OSS tree, and says the product is built on open source rather than being open source. [code.visualstudio.com/docs/supporting]

Price: The editor is free but the agents are not: reaching the Claude Code and Codex harnesses through a Copilot subscription starts at Copilot Pro, $10 per user a month. [github.com/features/copilot]

vibe-kanban

Sunsettinggithub.com

What it is: Vibe Kanban is an orchestrator, not an agent: each kanban issue gets its own branch, terminal and dev server, and the board drives 10 named coding agents including Claude Code, Codex, Copilot and OpenCode. [github.com/BloopAI/vibe-kanban]

Choose vibe-kanban when: Compare what two agents did to the same issue and comment on the diff without leaving the board. [github.com/BloopAI/vibe-kanban]

Where it hurts: The company behind it is gone: bloop announced its shutdown on 2026-04-10 because it could not find a business model. [vibekanban.com/blog/shutdown]

Price: Paid subscriptions were cancelled and refunded when bloop shut down on 2026-04-10; the local product now costs nothing. [vibekanban.com/blog/shutdown]

Vibe Kanban is sunsetting: its own README says so, bloop shut down on 2026-04-10, remote services ended 30 days later, and the repository has taken no commit for 117 days.

How we check this page

Stars, licences, the newest commit on each default branch and the latest stable release are read from the GitHub API, and each one shows the day it was last confirmed rather than the day this page was built. Every judgment and every price is quoted from a page we read, and that page is linked beside the claim. Where a link is missing we wrote no claim. We have researched 3 of the 14 tools named here.
