7 Open-Source Repos That Replace Cursor, Perplexity, and v0

7 open source repos that do what cursor, perplexity, and v0 do combined zero waitlists. zero api markups. zero vendor lock in. save the list: » openhands // agentic coding platform. plans, edits files, runs terminal commands, browses the web on its own. mit https://lnkd.in/gmxhbTCH » zed // rust-native ai editor. gpu-accelerated, ships the open agent client protocol so any agent can plug in. 86k stars https://lnkd.in/g_w75viP » codex // openai's official terminal coding agent. runs in network-isolated containers for secure work. 94k stars, apache 2.0 github.com/openai/codex » scira (formerly miniperplx) // minimalist perplexity alternative. citations, focus modes, built on vercel ai sdk. 11.7k stars https://lnkd.in/g7KdmvQg » morphic // open source answer engine with generative ui. streams charts and comparisons inline with the answer. mit github.com/miurla/morphic » december // self-hosted bolt.new. $5 in api credits gets you 50+ full app generations. docker deploy in one command https://lnkd.in/gihiCf7B » libra // cloudflare-native v0 and lovable alternative. serverless, free tier friendly, byok https://lnkd.in/gVg9cPyU closed source is losing this race quietly. star them before your feed catches on.

I verified each of the seven repos individually. All seven are real, existing open-source projects — but several specific details (star counts, licenses) show minor discrepancies worth flagging.

Confirmed accurate:

• OpenHands — real, MIT-licensed agentic coding platform; independently confirmed as an autonomous agent that plans, edits files, runs terminal commands, and browses the web. (No star count given in the post, so nothing to check there.)
• Zed — real, Rust-native, GPU-accelerated editor that co-created the Agent Client Protocol (ACP), letting external agents plug in. Star count is very close: multiple sources put it at ~85.8k–87.9k stars, matching the post's "86k" closely.
• Codex (OpenAI) — real, confirmed Apache-2.0 license, and the network-isolated container sandboxing claim is accurate (Codex uses OS-level sandboxing plus Docker with firewall rules blocking network egress). Star count is plausible: sources report it crossing ~85k-99k+ stars around mid-to-late 2026, so "94k" fits within that range depending on exact date.
• Scira (formerly MiniPerplx) — real, confirmed as a minimalist Perplexity alternative with citations, built on the Vercel AI SDK. Star growth from ~8.4k (mid-2025) to "11.7k" is plausible over time.
• Morphic — real, confirmed as an open-source answer engine with generative UI (streams inline components like charts/comparisons).
• December — real (ntegrals/december), confirmed as a self-hosted Bolt.new/Loveable/Replit alternative, Docker-deployable, with the specific claim that "$5 in API credits" generates many full apps — official sources say "dozens," which is in the same ballpark as the post's "50+" (slightly more generous but not a wild exaggeration).
• Libra — real (nextify-limited/libra), confirmed as a Cloudflare-native v0/Lovable alternative deployable via Cloudflare Workers with your own API keys (BYOK).

Discrepancy worth flagging:

• Morphic's license: the post says "MIT," but Morphic's own site and GitHub state it's licensed under Apache-2.0, not MIT. Similar permissive open-source license, different terms.
• Zed's core license: not mentioned in the post, but worth knowing — Zed's editor core is actually GPL-3.0-or-later (with Apache-2.0 components like GPUI), not a permissive MIT/Apache license, which matters if "zero vendor lock-in" is read as implying maximal license permissiveness.
• Scira's license: it's AGPL-3.0, not mentioned in the post but relevant to the "zero vendor lock-in" framing since AGPL has copyleft implications for hosted deployments.

Verdict: Every project named is real and reasonably well-described in function. Star counts are all in a plausible range (some possibly slightly rounded up). The one clear factual slip is Morphic's license (Apache-2.0, not MIT) — a small but checkable error.
