AgentGPT Is Archived - Here Are the Best Alternatives in 2026
AgentGPT's GitHub repo was archived on January 28, 2026. Read-only. No new commits. Over 130 issues sitting unanswered. Reworkd pivoted to web scraping back in July 2024 and never looked back.
If you're here, it's because there's not much left to build on. The $40/mo paid tier still shows up on pricing pages, but with the open-source repo frozen, there's no realistic path to fixes or ongoing maintenance. The demo still loads on GPT-3.5 - no Claude, no Gemini, no open-source models - but that's a museum exhibit, not a tool.
One Reddit user nailed it: "AgentGPT seems to excel at creating tasks for itself but fails to produce meaningful or useful output." Time to move on.
Our Picks (TL;DR)
- AutoGPT - closest open-source replacement, 183k GitHub stars, actively maintained, free to self-host
- CrewAI - modern multi-agent orchestration, open-source or from $25/mo hosted
- Prospeo - when your agents need verified B2B contact data to act on (98% email accuracy, free tier)
Switching agent frameworks won't fix bad data. Prospeo's enrichment API returns verified emails and direct dials at a 92% match rate - refreshed every 7 days, not every 6 weeks. Plug it into any agent workflow via Zapier, Make, or direct API.
Start with 75 free verified emails - no credit card required.
Top Alternatives Worth Switching To
AutoGPT
AutoGPT is the project AgentGPT wanted to be - 183k GitHub stars, 8,100+ commits, and a community that's still shipping code.
Setup isn't trivial. You need Docker, 8GB RAM minimum (16GB recommended), and 4+ CPU cores. But once it's running, AutoGPT is strong for sequential task chains and operational automation, especially when you want an agent to chain steps with internet access, memory, and file handling. We've found it handles research-and-summarize workflows surprisingly well once you nail the prompt structure, though anything requiring nuanced judgment still needs a human in the loop.
One critical warning: set step limits and budget caps before you start. AutoGPT can burn through OpenAI API credits fast without guardrails. Runaway loops are one of the most common complaints with early autonomous-agent setups, and we've seen test runs rack up $15+ in API costs in under an hour when left unchecked.
A cloud-hosted beta is in the works but still closed. For now, self-hosting is the path.
Price: Free (self-hosted). Cloud pricing TBD.
CrewAI
CrewAI takes a fundamentally different approach from AutoGPT's single-agent loop. Instead of one agent doing everything, you define multiple agents with specific roles - a "researcher" feeding findings to a "writer," orchestrated through role-based assignments. It's a Python framework built for multi-agent orchestration, and it's more accessible than LangGraph's graph-based approach.
Here's the thing: for most real-world use cases, the multi-agent pattern just works better than a single agent trying to do everything. You get cleaner outputs because each agent has a focused scope, and debugging is far easier when you can isolate which agent in the chain went sideways. The open-source version handles experimentation well, and paid plans start at $25/mo for hosted usage.
Price: Free (open-source) / $25/mo (hosted).
Prospeo
Your agent framework identifies targets. Prospeo gives it accurate data to act on.
Autonomous agents are only as useful as the data they're working with. If you're building agent workflows for B2B prospecting or outbound automation, the agent needs verified contact data - not stale CSVs from six months ago. Prospeo covers 300M+ professional profiles with 143M+ verified emails, 98% email accuracy, and 125M+ verified mobile numbers, all refreshed on a 7-day cycle versus the 6-week industry average.
The practical workflow looks like this: your agent framework identifies target accounts and roles, then Prospeo's enrichment API or Zapier/Make integrations feed it verified emails and direct dials. The 92% API match rate means your agents aren't wasting cycles on dead-end contacts. A free tier - 75 verified emails per month plus 100 Chrome extension credits - lets you wire it into a prototype without spending anything.
If you want to go deeper on list quality and workflows, pair this with a proper data enrichment process and basic email deliverability hygiene.
Price: Free tier (75 emails/mo) / ~$0.01 per email on paid plans.
AutoGPT and CrewAI handle the orchestration. Prospeo handles the contact data. 300M+ profiles, 143M+ verified emails at 98% accuracy, and 125M+ mobile numbers - all at ~$0.01 per email. Your agents stop wasting cycles on dead-end contacts.
Give your agents data that actually connects to real buyers.
Voiceflow
Voiceflow is the top SERP result for this topic, but let's be honest - it's a different category entirely. This is a no-code chatbot and conversational agent builder with a visual canvas. Think customer support bots and IVR flows, not autonomous task-completion agents. If you want an agent that goes off and researches, plans, and executes multi-step tasks on its own, skip Voiceflow. But for building polished conversational interfaces without code, it's solid.
Price: Pro at $60/mo per editor, Business at $150/mo per editor. Credits-based usage.
OpenAI Operator
$200/mo for an AI that controls a web browser. That's the pitch. Operator simulates mouse and keyboard input - clicking buttons, filling forms, navigating sites - and pauses for human confirmation on sensitive actions like logins and purchases. It works with partner sites like Instacart and DoorDash.
Interesting technology. But at that price point, most teams are better served by a proper agent framework plus API integrations that don't break every time a website changes its CSS.
Price: Requires ChatGPT Pro at $200/mo.
Devin
Devin is a coding-specific AI agent - writing code, debugging, running tests. Not general-purpose. An independent evaluation found Devin completed 3 out of 20 tasks successfully. That's a 15% success rate. Early-stage performance at a non-trivial price, and for teams that need coding assistance, tools like Cursor or GitHub Copilot deliver more consistent results at a fraction of the cost.
Price: Core at $20/mo + $2.25/ACU (1 ACU is roughly 15 min of active work). Team at $500/mo with 250 ACUs included.
Honorable Mentions
LangGraph is free, open-source, and part of the LangChain ecosystem. Built for stateful, multi-actor applications using cyclic graphs - powerful but steep learning curve. Best for developers already deep in LangChain.
SuperAGI starts at $9/mo and positions itself as a budget agent platform. We haven't tested it deeply enough to recommend it confidently, but it's worth a look if you're experimenting on a tight budget.
BabyAGI was another early autonomous agent loop from the same era as AgentGPT. It's best known as an endless-loop task system - skip it for anything serious.
Here's the uncomfortable truth most of these tools won't tell you: autonomous agent frameworks still fail more than they succeed. The real value right now isn't in fully autonomous agents. It's in semi-autonomous workflows where agents handle research and data gathering while humans make decisions. Build for that, and you'll actually ship something useful instead of watching an agent spin in circles burning API credits.
If you're using agents for outbound, it also helps to standardize your sales prospecting motion and keep a few proven sales follow-up templates ready.

FAQ
Is AgentGPT still free to use?
The demo still loads with 5 agents per day on GPT-3.5, but the repo was archived January 2026. The $40/mo paid tier still appears in pricing tables, but with the codebase read-only and 130+ unresolved issues, there's no path to fixes. It only supports OpenAI models - no way to swap in Claude, Gemini, or open-source LLMs.
What's the best free alternative?
AutoGPT is the strongest free option - open-source, 183k GitHub stars, actively maintained. Self-hosting requires Docker and 8GB+ RAM. For something lighter, CrewAI's open-source version handles multi-agent setups without the infrastructure overhead.
Can AI agents handle B2B prospecting?
Agent frameworks can automate research and outreach workflows, but they need accurate contact data to be useful. Without verified emails and direct dials, your agent is just generating bounce-backs. Prospeo's free tier (75 emails/mo) with 98% email accuracy gives agent-powered outbound the data quality it needs to actually convert.
Which replacement is best for non-developers?
Voiceflow is the only true no-code option, but it's built for conversational bots - not autonomous task agents. For autonomous capabilities without heavy coding, CrewAI's hosted plan at $25/mo offers a simpler setup than self-hosting AutoGPT, with a Python SDK that's approachable for anyone comfortable with basic scripting.
